Hello There,
After installing the theme, the thread topic is now showing and the top functions are not working.
All the yellow marks are not working expect the left side but they look transparent.
I've attached a screenshot 
Yikes!
Have you tried clearing your browser cache?
Do you have any errors in your Apache log files?
Please paste your software information into your reply

I've tried 3 different browsers and on mobile aswell.
Theme Information
osTicket v1.14.3 // osTicket-1.14.3-Awesome-101
The current version: osTicket-1.14.3-Awesome-101
PHP 7.3.16 // MySQL 5.6.40 // Apache web server
I will check Apache logs once I have PC access.
Thanks

nothing much
Hmmm I can't think what would cause that. Only one thing comes to mind... perhaps all the files didn't get extracted properly.
Please try downloading osTicket-1.14.3-Awesome-101.zip from the Downloads page and extracting it again. Overwrite the directories and files in your osTicket Awesome installation directory with the newly extracted files.
If you would like my assistance I am happy to take a look and get you sorted if you fill out this form with as much information as possible.
