Hey Marshae,
Thank you for reaching out, and I apologise for the trouble. That thread has since been resolved, and the steps below reflect what fixed it.
Regarding GoDaddy’s assessment: in that case, the error persisted on both PHP 8.3 and PHP 8.4, and disappeared without any PHP change. PHP version was not the cause there, so please do not stop at that explanation.
Quick Check
Confirm PHP version is 8.1+.
Confirm both Pro/X and Cornerstone are updated to the latest versions.
Confirm where the error appears — front end, wp-admin generally, or only a specific admin screen such as Appearance > Menus. This distinction narrows the cause considerably.
Troubleshooting
Reset your permalinks – Go to Settings > Permalinks and click Save Changes without altering anything. This regenerates the rewrite rules and is the step that resolved the identical report in the linked thread. Please try this first.
Increase PHP max input variables – In cPanel, open MultiPHP INI Editor and set max_input_vars to 5000. The default of 1000 is frequently exceeded on the Menus screen, as Pro loads the Cornerstone admin assets and icon library there.
Test with a default theme – Temporarily activate Twenty Twenty-Five, confirm the affected screen loads, then reactivate Pro. This tells us whether the error survives the permalink reset and isolates the theme as a factor rather than an assumption.
