Hello, I already tried to install a 5 times the ultimate helix and other templates based on the ultimate helix.
At all times I've done the installation, everything works normally, with only one problem that presents an error WHEN I TRY TO SAVE CHANGES IN THE TEMPLATE. (when I try to save the modification I made in the ultimate helix it gives me a message (Somethings wrong, Try again).
And the browser just keeps loading and I could not apply the modifications I made.
I already tried it on all browsers.
I already did a cache cleaning)
Due to this problem I always gave up using helix ultimate and I always went back to some Helix 3 template .
But now I'm going to use the Fixter template and need it to work perfectly. I do not only want you to solve the problem, but to teach you how to do it, because I will certainly have the same problems in future installations.
PS. The same error happened in PHP 5.x and even updating the server for PHP 7.x the problem kept happening.
