Update from 4.8.0 to 4.9.1 Internal Server Error.

Hi there! ??

Well, there are a few uncommon issues that can lead to internal server errors in WordPress. At first glance it could be that the memory limit of your site is too low, so asking your server to increase it could be the fix for it. Also, checking with them if there are any PHP Fatal error logs.

As a second step, this could be caused by a conflict with your theme or with another plugin.

The best way to determine this is to:

• Temporarily switch your theme to Storefront
• Disable all plugins except for WooCommerce
• Repeat the action that is causing the problem

If you’re not seeing the same problem after completing the conflict test, then you know the problem was with the plugins and/or theme you deactivated.

Before you start

1. First, please make sure you have a good backup in place of your full site and database. Most hosting companies have this included in the subscription, but you could also consider using a service like?Jetpack. If something goes wrong, it’s nice to know that you can restore your site.
2. Second, I would suggest installing a plugin called?Health Check & Troubleshooting. This is a plugin developed by the WordPress community and it allows you to disable plugins without affecting your current site visitors.

Regardless of that, what I usually recommend when users receive this error is to ask their host. As the issue could be a genuine server issue, that they can at least confirm and look at things like file permissions and other sources.

I hope this helps!
