operator not supported for strings on line

[Barzor]

I recently migrated to another server. No problems untill..
I suddenly get this error when I try to see a thread. Can somebody explain what this means?

[] operator not supported for strings on line 37 in /home/w12sdmo3osve/public_html/vb/ckeditor.php(74) : eval()'d code

It's caused by one of your plugins which uses the hook "editor_construct".
We can't see which plugin it is so you have to go to your AdminCP > plugin manager > find hook "editor_construct" and see which plugin it belongs to. If it belongs to multiple plugins, disable them one by one until it works.

Once you found the plugin that causes this, post the few lines that are around line 37 and maybe we can help you fix it.

Thanks Dave,

I found the plugin which causes the problem. Unfortunately its the one I really need for my business module.

I am using Hide Hack v4 which used to work just fine at my previous hosting that sucked. Now I am at godaddy I hope I can get to to work again

I had a look at the code, try the following:
Edit the hook of the plugin that's causing the problem, and find the following:

PHP Code:

$usergrouplist = ''; 


Replace it with

PHP Code:

$usergrouplist = array(); 


If you don't want to do that, you can try changing PHP version to 5.4/5.5/5.6. Seems that you are using PHP 7+?

Changing the code has no effect.

I can get into the thread page after I changed a setting but the threads are still empty, except for the title.

Changing the PHP version did the job
