Hallelujah! So glad you figured it out: thank you!
I added the debug mode code to functions.php as instructed, but no errors were detected, and the slider and buttons still aren’t working upon viewing pages. I tried setting up a test page with just a Fullwidth Easy Slider and a button, and they still don’t appear correctly.
Are there any other tools I can try to get this problem fixed? I included FTP credentials and links to the test page preview (appears correctly) and test page view (incomplete) in private content.
I did upload the theme via FTP, but there were no duplicated files in config-templatebuilder > aviashortcodes. I just deleted and replaced it with a fresh download, but the problem is still there. Is there anything else I can try?
The preview of the slider and buttons appears correctly, but when I view the public page, the slider doesn’t show up at all, and the button styling is incomplete.
