How to find a conflict
When you run into an issue, the first step is most often to test to see if anything on your site is interfering with Formidable to cause the issue.
- Deactivate all plugins except Formidable (deactivate addons too)
- Remove all custom code, including PHP and Javascript
- Switch to the default WordPress theme
- Update Formidable to the current version, if it isn't already
- Update WordPress to the current version, if it isn't already
- Clear all caching on your site and in your browser
- If you use a service like CloudFlare, put it in developer mode while testing
If the issue doesn't show up under these circumstances, you can add each item back in, one at a time, and test after adding each one until you find the culprit.
If the above steps don’t resolve the issue, try reverting to the previous version for Formidable Forms (Lite) and Formidable Forms.
Test on a staging site
If this is a live site, you can do the test on a copy of the site (a staging site), instead. If you put the staging site on staging.yoursite.com or dev.yoursite.com, you won't need an extra license for it.
Some hosts have an easy way to create a staging site. If yours doesn't, you can copy your site using free plugins like All in One WP Migration or Duplicator or any other plugin or system you like. Your host may be willing to create a staging site for you if you ask.
