I am sure an issue will be created on GitHub to fix the issue.

Forgive my ignorance, but will this fix also resolve this issue?

Or are they one in the same?

Many thanks!

Hi WordPress,

After updating to WordPress 5.5, Our payment portal which is developed in PHP were not working and its showing an error. Once we restore the backup then its working fine.

May i know what would be the issue with the PHP in WordPress 5.5 ?

Thanks.

Yeah, Classic Editor is still not working. I upgraded to 5.5 yesterday, and I am thinking of rolling back my WordPress version. Its unusable, and I am using Classic Editor 1.6. I uninstalled and reinstall classic editor, also clearing the cache between steps and no go.

Excuse my ignorance, @lukefiretoss but does the code you put here go into the functions PHP file?
