 * This is propably related to some other plugin or theme you have installed, as
   there are many users without such problems.
 * Please enable debug reporting or have a look into your error log and provide 
   some more details.
 * You could really help figuring out a plugin/theme related problem by disabling
   your used themes/plugins.

 * Apologies Adrian and thanks for the fast answer – this wasn’t meant to be a support
   request.
 * This was on a vanilla site with only Akismet and ‘Hello Dolly’ on it so I’m pretty
   sure it wasn’t the other plugins. Maybe some other change to my server has caused
   the problem. Anyway, quite likely others will find it works for them, as you 
   rightly say.

 * Ah, anyway thanks for the information.
 * I hate these kind of errors 😉 We already a specific server configuration issue
   once, which should be fixed in this version. Seems that there are more out there.
 * If you ever want me to give access, so I can try this on my own, contact me via

 * I tried the plugin on my localhosted test site and it didn’t work for me, I get“
   Fatal error: Call to protected TGM_Plugin_Activation::__construct() from invalid
   context in D:\xampp2\htdocs\VGP\wp-content\themes\Gameleon\includes\classes\class-
   tgm-plugin-activation.php on line 992”

 * Hello BuckoA51,
 * First, please open a separate support issue next time 😉
 * Regarding your issue. The problem is, that your theme provider seems to use an
   old version of TGM and therefor this error occurs. (The theme author should already
   be aware of this, as Envato informed all authors about this).
 * Unfortunatly, as a workaround you have to edit the file `wordpress-before-after-
   images-slider-lite.php` manually and remove the line: `require_once 'modules/
   tgm-plugin-activation.php';`
 * I currently don’t have an idea, on how to permanently solve this issue. So any
   idea is welcome 😉
 * Adrian
