My appointments system is currently not working for my users. It is loading forever or showing "500 internal server error".
It used to show an "out of memory error" so i increased my php memory limit (to 1024mb) and max execution time.
I'm on a VPS server, with 2gb ram and a quadcore processor... i guess i have enough ressources.
I also disabled all my plugins and tried to switch to another theme (still doesn't work).
How can I solve this?
Thank you !
