Hi Corinne,
I understand your frustration, but I believe changing theme won’t resolve your issue.
The Internal Server Error is inconsistent, I did not get that error at first when I check your site, I did after I installed the WP-ServerInfo plugin, if its a Theme issue then we will get that error all the time until we deactivate the theme, make sense? And if it is a PHP error then it should be log on the debug.log
file, but it’s not. the last error from that log is from 11-Jan-2019.
And if we take a closer look on that log, we will see the wp-super-cache is causing the error. So I did try disabling the W3 Total Cache Edge Mode in the wp-config.php file, and that made the site back up again, so the wp-super-cache is partly involved on this, maybe you did not clear the cache after you update the Wordpress and/or the Theme.
Remember to clear all your caching features (plugin, server-side, CDN, and browser’s cache) after updating so that the code from the latest release is always in use. This will help you to avoid any potential errors.
Another thing, you already install an SSL certificate on your site (https://www.cjchrservices.com/
), but the URL you have on Settings > General is still http://www.cjchrservices.com
(not https://), so consider this as part of the issue, to resolve this please follow this thread.
And another issue that can be solved by that Better Search Replace solution is, even though your site is now live its still requesting resources from the staging URL (http://www.cjchrservices.dreamhosters.com
)
The 404 status code means that resources do not exist. This more likely the reason why we get Internal Server Error when we try to edit a page.
Please do the Better Search Replace solution, remember to backup your database first, ask your hosting for assistance.
Let us know how it goes,
Thanks,
