Hello there,

PHP resources

Since WordPress themes get more robust and complex, it's necessary that you release some more power from server. You can do that by editing php.ini file that you can find on your server, or contact your hosting service to do this for you. 

Make sure you meet these requrements:

max_execution_time = 300;
memory_limit = 128M;
upload_max_filesize = 128M;
post_max_size = 256M;

PHP version

You should also make sure PHP version on your server is updated. 

5.6 will do the job, but you may use 7 as well.

Also, it is possible that something has not been installed/adjusted correctly, or it can be that some 3rd party plugin causes this issue.

Try to deactivate all of your plugins to make sure they are not causing this issue. If the issue goes away, then you can enable them one by one to find out which one is causing the issue. If you still have issues after you have deactivated all of your plugins, please provide a temporary admin login and URL to your site and I’ll take a look.

Check these and if the problem is still there, let us know, and if you still have this problem give us WordPress admin access and share a link to a page with issue so we can check this on your end.

Hello there,

Right now when we try to add gallery images, we can't add larger amount like 16 for example, because of WordPress core error https://www.screencast.com/t/ItuPeDsP , but if we try to add 3 by 3 to gallery then you should manage to add items to gallery like we did in an example on this page http://sybilrondeau.com/gallery-test-page/ . 

Sometimes it is possible that something has not been installed/adjusted correctly, or it can be that some 3rd party plugin causes this issue. Try to deactivate all of your plugins to make sure they are not causing this issue. If the issue goes away, then you can enable them one by one to find out which one is causing the issue. If you still have issues after you have deactivated all of your plugins, please provide a temporary admin login and URL to your site and I’ll take a look.

Also, ask hosting support about that error to see if it is something related to SSL configuration or something else.

Best Regards!

Hello there,

In this video we have recorded action of adding images to the gallery. https://www.screencast.com/t/9lArghxVl Here is working just fine. If you encounter issue again when adding images to existing gallery you will certainly see error which we have mentioned earlier so try adding image with Chrome browser developer console open (keyboard F12). If you encounter that error then please disabling all plugins as we already suggested and also try to contact hosting support since we can't replicate same kind of error in our testing environment.

Hello again,

We test on recompense page and it's working. You can see it in the video that we recorded. https://www.screencast.com/t/kNpYadKOV

Since this works on our side, and only error related to this is from WordPress core script we have suggested your to contact host regarding that error https://www.screencast.com/t/ItuPeDsP and to see some articles about it:

Server environment and errors like this one are not our line of expertise so we really hope that hosting support is much more familiar with such issues and that they will be able to assist.

Best Regards!
