Please can you help? I am getting the following error after launching Cornerstone: “The preview could not load. This is most often related to a plugin conflict or aggressive page cacheing. Checking the developer console for errors could indicate what went wrong.”
I have tried all the steps specified in your previous posts on this matter: update all software; disable plugins, increase memory.
It seems that you server is running older versions. Please ensure that you have meet the minimum requirements to run WordPress core. You may need to update your PHP version to 7.2.
Please check this out:
Meanwhile, I have checked the pages and edited some of them. It loads on my end.
I edited your about us page and it seems it empty. You may have edited this page outside of Cornerstone. Please be advised that you are not allowed to switched between editors. Pages created with Cornerstone should be edited in Cornerstone only. using other editor like the default WP editor might corrupt the cornerstone data which may no longer allow you to edit the page back in Cornerstone.
If you happen to experience the caching error in the preview, you can also use the skeleton mode to edit the page for faster response and easy access of the elements on the preview area.
Many thanks for your help. The skeleton mode worked I am now in contact with the ISP and hope they will advise regarding PHP version and memory allocation.
