Ok it is solved by correctly configuring the memory limit of the site on the server, some hosts don’t let the sites choose the memory limit thorugh wp-config.php, and after changing it need a restart to refresh them, thanks Bogdan B. for the help!

Ok i increased php memory limit to 512 MB, on my wp-config.php also configured it by adding define(‘WP_MEMORY_LIMIT’, ‘512M’);
define( ‘WP_MAX_MEMORY_LIMIT’, ‘512M’ );

still the same problem.
Except for the Category Order and Taxonomy plugins, i only have the ones required by the theme to work, tried deactivating all of them and activating, also no changes to de error.

After activating the debug log this is the error logged in debug.log:
[31-Aug-2018 14:56:14 UTC] PHP Fatal error: Allowed memory size of 67108864 bytes exhausted (tried to allocate 82 bytes) in /home/…

I don’t really know what else to do with the memory configuration to try to solve it.
