Would really appreciate an update on this issue.

Thanks!

I am having the same issue as well, can no longer load settings page – it brings a blank page back

@iodic: It seems that for some reason, the composer autoload isnt working on your system.

The autoloader is included like this in TestRun.php:

include_once __DIR__ . '/../../vendor/autoload.php';

And from there, it should handle loading the classes in the /vendor folder, when needed.

However, you get a “class not found” error, which is triggered when one of these classes are called.

Did you download WebP Express through wordpress, or from github? If the latter is the case, then the problem is simply that the ‘vendor’ folder is not distributed on github – you then need to run composer update to pull it in.

I’ve installed via wordpress and get a blank page when clicking settings – any ideas?

@roselldk Is it require any server module? Because the same plugin is working fine on my dev server and it arises issue on my live site.

It happens if you are running PHP < 5.5 – see https://www.ads-software.com/support/topic/error-on-settings-page-9/#post-11466666

@roselldk My live site running on 7.0.33-0ubuntu0.16.04.4 PHP version.
