I have problems with Cornerstone 3.0.4. It feezes when I click the edit-button to open the Editor of any page. The loading bar on the top of the page stops and does not reach the end. Then nothing happens.
I changed this settings to:
define( 'WP_MEMORY_LIMIT', '512M' );
define( 'WP_MAX_MEMORY_LIMIT', '512M' );
But I did not manage to set PHP Max Execution Time to 300.
My PHP Version: v7.0.27-0+deb9u1
X-Theme Version: 6.0.4
I also tried to deactivate my plugins, which did not help.
But I made this workaround:
To edit my pages I deactivate Cornerstone 3.0.4. and activate an old Cornerstone 2.0.5 plugin. The editor of this version works fine. After I am finished, I switch back to 3.0.4. But this is not a good solution. Besides my articles do not appear on my main page by using 2.0.5. Maybe it is incompatible with X-Theme 6.0.4. So I have to switch back to Cornerstone
3.0.4. and to deactivate 2.0.5. again.
Thank you for helping me.
