Vertical title in editor

possibly caused by a plugin, which adds more columns into the dashboard.

try deactivating all plugins, and then reactivate one plugin at a time and check for the error.

Hi,
You need to just minimize the columns from screen options in header and unchecked some unnecessary columns like SEO, Tags, Comments etc.
Hope you will find a solution to this.

Awesome, that worked. Thank you very much!
Kind regards.

Always Welcome!!
It’s my pleasure to help someone anyhow.
