Issue after upgrading Kentico 8.0 to 8.1

Tomasz Czado asked on July 6, 2017 22:31


I just upgraded Kentico 8.0 to Kentico 8.1. Upgrade tool did it without any issues. Database is up to date or at least in settings sql table I see 8.1 version. But when I logged in to Admin, I see top black panel and white space below it. Nothing else. I can't click on anything.

When I opened developer tools, I see below error in logs: "ReferenceError: $cmsj is not defined[Learn More]"

I cleared browser cache, build project, reset IIS and removed framework temporary files.

What should I do to fix it?

I resolved it. When upgrading K80 to K81, tool updates some of the files but not files that has been modified. jquert-core was one of them. Because new lib has jquery alias set to $cmsj (noconflict) instead of $j so that's why it wasn't updated and caused an issue.

Thaks for all answers.

Did you check the events log to See two entries "Upgrade started successfully" and "Upgrade completed successfully"? Not exactly these words however very close to this.

Thanks, Chetan

You have a Jquery loading error where a reference to the JQuery is not loading. Check your jquery reference in your templates or wherever you load your Jquery reference. Here is some more info that might help.
