500 Error on New Post/Page

@ Tony

It seems unlikely Connections would be the cause because it does not do anything during a post/page save. Well, there is one small this it does, it check for the [connections] shortcode and cleans up common errors. But that only occurs when the shortcode is on the page.

Perhaps there is somehow a conflict with another plugin where this manifests only when both are active during a save. Have you tried deactivating other plugins while Connections is activate?

Please create a temp admin account with this plugin:

Reply back, as a private reply, with the token login URL. I’ll take a closer look and hope fully find the cause and solution.

Great to hear you were able to resolve the issue!

Connections does not require PHP version 7.1, but like WordPress itself, it does run faster using less resources.

Here’s an example…

I was assisting another user the last week which had the memory limit set to 256MB, but the web host was “hard” limiting usage to about 170MB. Meaning as a user you could set any high value and PHP would report that value but the web host would only allow 170MB of actual usage.

This user had Divi, JetPack and WooCommerce and a few other small plugins activated. Even without Connections installed and activated most of the available memory was in use. Activating Connections put the user over the limit in some cases like the directory page, where more memory would be required, and intermittently on the Manage admin page. Everything else seemed to work fine.

I have been modernizing the code base in the last many updates which does use slightly more memory on older version of PHP. So, perhaps, your available resources were already borderline and the latest changes just push it over the edge.

Also keep in mind, other plugin you install also take resources and if there are updates which add features, this also increase resource requirements.

Hope this helps, explain it the issue better!
