After updating from ACF Pro 6.3.9 to 6.3.10, I get this fatal error when attempting to access any page in wp-admin:
An error of type E_ERROR was caused on line 812 of the file /home/…/plugins/advanced-custom-fields-pro/acf.php. Error message: Cannot redeclare acf_updates() (previously declared in /home/…/plugins/acf-flexible-content/acf-flexible-content-update.php:433)
Downgrading to ACF Pro 6.3.9 relieves the error.
6.3.10 did the same thing to my site and gave the same error. I downgraded to 6.3.9 to resolve it.
@haabda From what I’m reading, since we have ACF PRO we should not need the Flexible Content Add-on because that functionality is included in ACF PRO. The add-on is no longer supported and no longer available to install as a separate plugin. So I feel like the right solution is to simply disable the plugin Advanced Custom Fields: Flexible Content Field, but I’m a little hesitant to do that on my very actively used live site. If you try it, please post back and let me know!
This solved my problem. I deactivated the following redundant plugins:
• Advanced Custom Fields: Flexible Content Field
• Advanced Custom Fields: Repeater Field
These are very old plugins that are no longer offered nor supported. Their functionality in included in Advanced Custom Fields PRO, so they are redundant.
After deactivating the 2 plugins, I updated ACF PRO to 6.3.10 and there is no fatal error. I then tested functionality by editing posts that included flexible content and repeater fields. All works well. Simple solution for me.
I disabled ACF: Gallery Field, ACF: Options Page, and ACF: Repeater Field. Then I was able to update to ACF Pro. Thanks for the help.
