Help, can't login to wp-admin, getting HTTP500 error

Try checking your site’s error logs for a more specific error message. Your hosts should be able to help you accessing your site’s error logs.

Hi Esmi, thanks for your reply, I’ve spoken to my hostingprovider, they can’t see what’s wrong up front. So now they’ve assigned my support request to another department who hopefully will determine what’s wrong. Meanwhile I’m lookin at a possible solution I’ve read: changing the .htaccess file.
Now it looks like this:

# BEGIN WordPress
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /
RewriteRule ^index\.php$ – [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /index.php [L]
</IfModule>

# END WordPress

Before I change anything (and mess things up) I would like to know if this is already the right code or what changes I could make.
I’m really at a loss here (sigh)…

So now, I got mail from Jetpack, saying that my site is online again BUT , when I try to go to the site or log in to the wp-admin I get a syntax error :

Parse error: syntax error, unexpected ‘<‘, expecting ‘)’ in /var/www/02/69/51/shmamassage.nl/www/wp-content/themes/tempera/admin/defaults.php on line 230

Can anyone tell me what to do now? Please!!

Did you make any changes in the template files yourself?

This error is related to code and sharing the defaults.php may help in resolving this.

I’m now able to login to wp-admin, But Something is terribly wrong, because this is what I read:

Notice: has_cap was called with an argument that is deprecated since version 2.0! Usage of user levels by plugins and themes is deprecated. Use roles and capabilities instead. in /var/www/02/69/51/shmamassage.nl/www/wp-includes/functions.php on line 3193

Also : the theme I was using : Tempera, is not complete, it has no Style sheet!! How is this possible?
If I try to upload the theme again, it says I’ve already installed it.

Apply the default theme or any other available theme. Remove this folder of Tempera theme and then try to upload.

If you don’t delete the existing Tempera folder, then it won’t let you upload it.

Hi Meraj! Tnx, I couldn’t delete the Tempera theme in my dashboard (jet another strange thing going on), but I deleted the file in the FTP c.panel. And that worked.
So now I uploaded the theme again! Happy with that. But the drama continuous..

Now this appears:

All of these notices!! On every page!! Where the H. did they come from and more importantly: How do I get rid of them???

I already looked at the pages and posts and found nothing ‘out of place’ there.

Deactivate the wp-socializer plugin.

Yes. Deactivate the wp-socializer plugin and also ask your hosting provider to not display php code errors or notices but instead log them to a file.

Ideally a production server shouldn’t show such notices, it is not a good practice.

Okay, I read that the notices may be caused by an outdated plugin.
So I deactivated the plugin. That took care of that.

But now a notice apppears on my about me page (‘over mij’ in Dutch)
this is the notice :

Notice: Undefined offset: 0 in /var/www/02/69/51/shmamassage.nl/www/wp-content/plugins/seo-image/seo-friendly-images.php on line 205

On this page :
https://www.shmamassage.nl/over-mij

Strange thing: this notice is only on this page.
Help!! I can’t keep deactivating plugins????

I looked up the issue regarding notices and warnings: It seems that there is a way to disable the notices and warnings in the php ini file?

Any ideas where the file is and what it should say or how to configure it?

Hi,

I read in several posts that in order to disable notices and warnings, I should turn the wp-debugger off.
So that’s what I did, and my website is back to ‘normal’ (at least it looks that way).
I Still don’t know what the warnings and notice were about, but now I can pick up where I left off : setting up my website.

I’m very thankful for all of your help with this, esmi and meraj.khattak, you’ve made me feel less alone in this drama.

I’ll mark this post as resolved.

Tnx once again!!
