[Bug / Issue] Updating 5.5.1 to 5.5.2 fails: JavaScript not enabled (while it actually is)

[m97forum]

Hello,

I'm trying to update my current vB 5.5.1 to current version 5.5.2. Upon calling the update script, I have to enter my license code and start the process. But then I get an error message, stating that no JavaScript is enabled. I'm also requested to check the availability of file https://HOST/install/vbulletin-upgrade.js - which is available.

1. vBulletin Version: 5.5.2
2. PHP Version: 7.7.2
3. MySQL Version: 5.6.19
4. Any Addons installed: no
5. Does the issue occur in a default style? think so
6. Does the issue occur using the English language provided? yes
7. Error message on the screen':

Startup Errors
Due to the following errors, the install/upgrade can not continue:

   4. Opera 60.0.3255.170
2. Did you clear the browser cache and did the error continue? yes
3. A list of steps that can be used to recreate the issue.
   1. upload files
   2. access https://HOST/install/upgrade.php
   3. enter license code
   4. start the process
4. If the issue is an Invalid Server response, the web server and PHP logs that correspond with its timestamp.

Any ideas? Any other update I've done finished successful.

Thanks a lot.

What ad blocking extensions are you using in your browser?

Hello Wayne,

I have no such extensions installed in Firefox, Chrome or Internet Explorer. I do have the Opera Ad Blocker installed. Default settings do apply here, as well as Do Not Track and Cookie settings (remove upon close).
