thanks for the quick fix. I mad a donation, it should have arrived 1h ago :-). I hope that the amount is fine. Currently, you have the best view on my server, so no more feedback from my side, as long as you have seen other things that crash oder are not set properly. What's the release date for the 1.5.x branch?
Another thing: do you reasons for very slow Wordpress backend performances? Frontend ist nice, but the backend from clicking from one menu point to another takes decades. OPCACHE is active, PHP 7.1 is used instead of 5.6, I have a own VPS with SSD. I have no idea. MariaDB is 300MByte in size. Honestly, I do not why it's so big, but it's on SSD.
