Hi, it is nearly working for me, but I get following error:

PHP Warning:  require_once(/***/wp-load.php): failed to open stream: No such file or directory in /***/wp-content/plugins/picasa-express-x2/picasa-express-2.php on line 3438
PHP Fatal error:  require_once(): Failed opening required '/***/wp-load.php' (include_path='.:/***/usr/***:/***/usr/share/pear') in /***/wp-content/plugins/picasa-express-x2/picasa-express-2.php on line 3438

I’m using latest WP 4.2.2 version
Please, Could you help? I really need this plugin working again.

Hi avatarone1,

thanks for your effort to fix that problem. I followed your steps exactly and finally (after some errors I made) the plugin was working again!

Next thing for me to do is to donate an amount to your Paypal account!

Hopefully Google will not change again something!!

Hope to keep in contact

Regards

Stefan

Hi,

thanks for all , google doesn’t prefer to change anything but Authsub is out of date and google warns for cancelling it for months ,

@redywebs this problem is not related to this fix , I thought to change this part of php code but I preferred to change auth part only.

this problem occur when you change the path of wordpress or move to another host or any thing that change the real path of the plugin folder.
this problem is a clear mistake from the author but he didn’t think about it

so to fix this :
method 1 : just delete pe2-wp-path.php file which included with the plugin folder.

method 2 (you will have to do this on every time you change the real path of the plugin folder):
(if you doesn’t know the real path ,do another solution)
open pe2-wp-path.php file which included with the plugin folder (this file generated on first install of the plugin) and change the path to the correct path (real path from the user root not http path).

method 3 (this will fix the problem permanently):
just delete this part from the php code

if(file_exists(dirname(__FILE__).'/pe2-wp-path.php')){
// include the pe2-wp-path.php to define the wordpress root
// (this allows a customized path (sometimes necessary in certain
// wordpress installations) to be set when saving the pe2 preferences page
// and written to the file system so it can be loaded here prior
// to any wordpress filters or functionality being available)
// (using an include that sets a variable so that if the file is
// accessed from the web nothing is visible, thus not causing a
// security problem)
include(dirname(__FILE__).'/pe2-wp-path.php');
}

method 4 (this will fix the problem permanently, if I typed this plugin I would do this , it is the same idea of method 3):

delete this :

// require wp-load so that wordpress loads allowing us to perform the updates
// to the appropriate setting
if(file_exists(dirname(__FILE__).'/pe2-wp-path.php')){
// include the pe2-wp-path.php to define the wordpress root
// (this allows a customized path (sometimes necessary in certain
// wordpress installations) to be set when saving the pe2 preferences page
// and written to the file system so it can be loaded here prior
// to any wordpress filters or functionality being available)
// (using an include that sets a variable so that if the file is
// accessed from the web nothing is visible, thus not causing a
// security problem)
include(dirname(__FILE__).'/pe2-wp-path.php');
}
if(!isset($pe2_wp_path)){
// for some reason the include doesn't exist (preferences haven't
// been written, or web server doesn't have write access to the
// plugin directory) or the include didn't set the appropriate
// variable.
// We have no choice but to determine the path as best as we can
// and hope it works with this installation
$pe2_wp_path = preg_replace('/wp-content.*/','',__FILE__);
}
// require wp-load.php for the core wordpress functions we need
require_once($pe2_wp_path.'wp-load.php');

and put this instead :

// require wp-load so that wordpress loads allowing us to perform the updates
$parse_uri = explode('wp-content',__FILE__);
require_once( $parse_uri[0] . 'wp-load.php' );

—–
if anyone has any other problem , please post it.
I think it will not be any another problem ,this last problem I have already expected it and it doesn’t relate to the auth fix.

to anyone have or will have this problem ,I recommend method 3 or method 4 .

I have made this file has (auth fix as the main post of the topic + require wp-load.php fix)
https://drive.google.com/file/d/0BxJDmNzyAfLhS29JNVQzR1NUTkE/view?usp=sharing

I recommend to use this file instead of the picasa-express-2.php file of the main post to avoid any future problems.

N.B : there is no relation between auth fix and require wp-load.php fix.

Hi there – it seems I have been a little bit too enthusiastic ??

I found out that this solution only works temporary. After some time, when I open my homepage, i get no pics from my picasa albums and get the message “response code is 403”.

To solve this I have to go to settings of the “Picasa and Google plus Express”-Plugin. I get the error message there as well “Checking user: error: Response code is 403”.

All I have to do is “Revoke access…” and “Request access…” – after this is done i get the message in the settings “Checking user: ok”

The pictures than appears on my homepage.

BUT – after a specific time (I didnt find out yet how long it is exactly) – everything starts from the beginning with no pics on my homepage and “response code is 403”

Do you have any idea what this can be?

Thanks for your help!

Stefan

@heimatpfleger thank you for your feedback
this was a mistake ,I have forget to update the code of blog level
the code already was working for user level
mostly you tried blog level so this error occur

now I have updated the files you can replace the new files (save info part before this)
please test the updated code and tell me the result

also, I will make the console client info fields on the plugin setting page to make this easier and to support multisite install but I am very busy for days I will do this later.

sorry I intended to say
the code already was working for blog level
mostly you tried user level so this error occur

tested for blog and user level and it works for both !!
N.B :
-you must revoke access then request a new access when changing between blog and user levels.
-I have updated the files on google drive , you can download it from links in previous posts.

Hi Avatarone,

I’m using the last version provided but right after authentication I get this:

Fatal error: Call to undefined function register_activation_hook() in /home/xxx/public_html/<mydomain>.com/blog/wp-content/plugins/picasa-express-x2/picasa-express-2.php on line 148

The same error is now with the original plugin file.

The lines giving error are:

register_activation_hook( __FILE__, array (&$this, ‘init_options’ ) );
register_deactivation_hook( __FILE__, array (&$this, ‘delete_options’ ) );

I can’t understand why the functions aren’t loaded.

Hi dabesa,

this can’t be related to my auth part change , this is a big error may be related to your multisite install or may be the plugin has an error related to multisite install.

try to deactivate the plugin then activate it or please search because I didn’t have much information about multisite install problems.

at the end of this week I will make a different thing on the solution , wait,support me , and post any problems you get.

Hi,

as I promised I have updated the plugin again but this time I have made a 3 options of OAuth2 in the setting page of the plugin.
from now there is no need to edit anything on the php file of the plugin.
I have made a simple app to serve the OAuth2 (get code , get access token , refresh access token) for any website , so no need for console project if you want it easy.
the 3 options of oAuth2 is :
Default App : it is the app deployed by me on console project and it is encrypted.
Custom App : you can upload your app and use it instead of default app , you have to edit the file and add a client id info.
Client ID : if you want to make a console project and use it.

to download this app if you want to upload it and using it as a custom app :
https://drive.google.com/file/d/0BxJDmNzyAfLhcVRYTDJVNV91YU0/view?usp=sharing
this app may be very helpfull on multisite install.

to download only the new picasa-express-2.php file :
https://drive.google.com/file/d/0BxJDmNzyAfLhekRWSDRVbnhiTkk/view?usp=sharing
to download the full updated plugin :
https://drive.google.com/file/d/0BxJDmNzyAfLhV3BQS3RVMFM2OWc/view?usp=sharing

Take a look on it , you will be happy !!
I expect that this is the final wonderful update ??

Hi Avatorone1,

Thanks very much for looking into this issue, it’s a life-saver!

However, when I try and use the latest version of the plugin, with either “Default App” or “Client ID”, trying to authorize fails. I get the Google “Approve” screen for my application, but after that I get this error:

{“error”:{“message”:”Invalid verification code format.”,”type”:”OAuthException”,”code”:100}}

I don’t know why it’s mentioning Facebook!

Any thoughts please?

Thanks!
