- Test for a plugin conflict. You can do this by deactivating all third-party plugins, and see if the problem remains. If it's fixed, you'll know a plugin caused the problem, and you can narrow down which one by reactivating them one at a time.
- Reset your htaccess file by renaming it to
.htaccess-bak. Then in WP Admin Menu, go to Settings > Permalinks and just click the Save Changes button.
- Make sure that you're running at least PHP v5.6.x or later to avoid any WordPress related incompatibility issues.

120 for optimal usage (https://thimpress.com/knowledge-base/how-to-increase-maximum-execution-time-for-wordpress-site/).
