Live site subpages show error:

Not Found
The requested URL was not found on this server.

Apache/2.4.41 (Unix) Server at www.perthcentre.co.uk Port 80

Background:

I have access to a local site with the same data used on the live site. I have access to control panel for the latter but haven’t changed anything since gaining access rights from the hosting administrator. I have only scanned the site.

I have searched for info on how to reverse this, and even though i have been successful diagnosing previous matriculation issues on WP, i seem way out of my depth with this one.

There is a fella who has primary acess to the control panel who i would normally turn to for help, but he is diffcult to get a hold of.

Can anyone help?

My end goal is to migrate data from approved changes on test site to live site with least amount of hiccups as possible. I wanna simply play about with and customise migrated theme features and block editors etc, whilst also realising the limits that my abilities limit me to in the process.

I may forget some minor but important details with my explanations here so forgive me.

Any further suggestions and tips for me to make the best use possible out of my time here would be greatly appreciated.

Only way to get around is to remove the plugin and then login

I’ve noticed that my website has been abnormally slow since I installed Above-The-Fold Optimization. I used it in the past for other WordPress websites, but for this one I keep getting this error in my Server Logs :

AH01071: Got error 'PHP message: PHP Warning: Invalid argument supplied for foreach() in /var/www/vhosts/andamancoraldivers.com/httpdocs/wp-content/plugins/above-the-fold-optimization/includes/optimization.class.php on line 452\n'

My website usually loads in 2.5-3seconds, but when this Warning/Error pops up the site loads in 10-15 seconds, or even sometimes gives out a 504 Error. The issue stops when I disable the plugin though.

I’ve checked with my theme developer and they verified that this issues is not related to the theme but rather this plugin. I look forward to the fix!

Using the interface I could create 4 different galleries and make a album of it in the last week.

When I tried to create a new gallery and upload image, it does not allow to do so. The message found in apache log file is — [ [Thu Jun 04 02:58:46 2015] [warn] [client 115.114.17.146] (70014)End of file found: mod_fcgid: can’t get data from http client,
referer: URL…../wp-admin/admin.php?page=ngg_addgallery ]

Is it related to — fastcgi maximum upload time ?

Is there any restriction on number of galleries created OR number of images that can be uploaded?

The images used for upload are of .jpg types and the file size is in the range of 35 KB to 145 KB.

Can you please help out for this error?
