I’m a semi-regular contributor on WordPress Support Forums. & as you develop and assist more, you realize that theres a basic troubleshooting routine to solve almost all vague/inexplicable problems – you typically do the same things. These problems include;
- /wp-admin/ not loading
- Unable to drag and drop in dashboard
- White screen instead of site
- Unable to use Visual tab
Basically anything not normal or anything not working properly (that is not directly related to installing or using a new plugin. To get your WordPress site back online, here’s a breakdown of how to troubleshoot to find the issue:
- Visit your error log to reveal PHP errors
wp_DEBUGon to reveal MySQL + PHP errors on your WordPress site
- Disable all plugins one-by-one to find the culprit
- Disable your theme, revert to Twenty-x
- Upload WordPress to fix any permissions or file errors (except
- Comment out any
.htaccessfirewalls or non-WordPress rewrites
If any of these techniques work, refer to basic Google’ing on how to resolve the issue. Open source software controlling 25% of the web, the odds are in your favour that someone experienced it too and wrote about it.
For overly basic example; if you discover plugin FooBar was not allowing drag and drop to work in the backend, search “WordPress FooBar drag and drop not working” – and you should find your answer.
Doing the troubleshooting in the order should eliminate any “I know it‘s my theme, but I don’t know what’s not working” issues, your problem will likely spit out in PHP errors.
