Post Upgrade to 7.13.0 - Error when clicking on Home Page/Spaces

[TARIQ PATHAN]

Dear Atlassian Community,

Our documentation is hosted on Wiki Server Subscription, Version 7.12.2.

This had some 'Security' issues on 7.12.2 version such as 'too slow' and sometimes 'documentation portal' totally inaccessible and down. Identified there are security issues for some of the Wiki Confluence Versions and these are fixed in 7.13.0. Researched and got to know, we need to upgrade to 7.13.0.

We built-up a Staging Server already (to test first on test instance, which is advised always) and then tried an upgrade from 7.12.2 TO 7.13.0 on Staging server.

Post upgrading to 7.13.0, when we click on Home Page/Spaces link, errors are reported in the backside 'errorlog file'. Attached is the .txt file which has errors listed for reference.

Appreciate help if any on this. Most of these as seen are related to some plugins related to k15t addon and thoughtworks. 

Please share your expert advice on how to fix this issue, post upgrading to 7.13.0.

It is a little critical, hence solutions provided at the earliest would be appreciated !

Best Regards,

Tariq

Hi,

have you tried to contact directly K15t support about this problem? They have probably a lot of experience with these kind of errors.
