Hi @israfil01
until I will finish updating the Sticky Heder plugin on the WordPress repository
You can try out the Beta version before the next update.
I strongly recommend checking the updated version, and let me know if there are any issues.
Thank you very much for your feedback.
I do believe the problem is solved.
You can download the beta version from here:
