XF 1.5 Unable to use search in admin panel

[Cirno]

Hello,

Whenever I click on the "search" button in my admin panel, nothing happens.

This is the image button in question.

Here's what I've tried so far:

• Disabled all my addons from the add-ons page
• Turned off the apache2 mod pagespeed
• Used different browsers (chrome and edge)
• Gone to the /install directory and clicked "rebuild master data"
• Done a file health check

I'm running xenforo 1.5.7 currently.

Any help or advice is greatly appreciated!

Please update xenForo 1.5.16a for security and solution

I'm using version 1.5.7 right now, isn't that a more recent version?

No, that's an older version.

Version 1.5.16a is the most recent.
