Reply To: Half day not available, then plugin crashed

I found the problem now: Directly after uploading it deletes the main easyreservations.php file with that wordpress loads the plugin. I have no idea why that happens and never experienced something like that. All I can say that it’s defiantly not by easyreservations. Either you have done another change or some security function doesn’t like the actual easyreservations.php (but there were no changes since 3.3).
There’s an folder for network plugins (mu-plugins) with a plugin named “disable plugins”. I tried to disable that as well as the WP Security plugin but easyreservations.php still gets deleted.
