Facing the PHP Fatal error: Uncaught Error: Call to undefined method FLBuilderAJAX::doing_ajax() after updating Beaver Builder after updating Beaver Builder to the latest version?
Here is the fix.
If the Beaver Builder plugin is outdated you might come across this Fatal error after updating the Ultimate Addons for Beaver Builder plugin. More details about the issue below:
In Ultimate Addons for Beaver Builder version 1.8.3, we have referred to a function in Beaver Builder which is present in Beaver Builder version 2.0.7 or above. If you’re using an outdated version of Beaver Builder or version below 2.0.7 you’re be seeing this error.
If you’re using the Beaver Builder plugin older than that, this issue will be obvious.
Check for any updates using the Force Check option from the WordPress Dashboard under Updates. You can refer the Beaver Builder changelog for the latest version. Or you can download the zip file of the Beaver Builder’s latest version and replace the previous version to resolve this issue. Make sure you delete the previous version while uploading the new zip file otherwise, you will get a file already exists error while uploading the plugin.
