Im using moodle 2.8 with essential and some customised themes. I had just added a new category with new category icon settings at custom CSS portion of essential theme, and suddenly ALL my custom settings is gone, the color, the icons, everything. This even affected my other custom themes using clean theme.
I tried to switch to different theme, it loads with NO css settings as earlier. I even reboot the server twice.
JUst to give you an idea, below is the screen, you can see even the little icons at side bar menu is not showing:
Also just to share, I am using Basic VM, 1 core & 1.75G RAM. Is this sufficient to be accessed by users? For my own admin access, I am experiencing significant slowness over the site.
I also tried to change to debugging mode, but i see no error on the main page.
What is wrong? I surely did not add/remove anything other than the category icon settings.
