Issue with Subversion Access Panel

[Venkat Dinakar]

Hi,

I am facing trouble with Subversion Access panel.

Currently we are using Trac version 0.12.7 along with SVN 1.7.22 & Python 2.6 on “Scientific Linux CERN SLC release 6.10 (Carbon)” OS.

Due to Scientific Linux End Of extended Life support by 30th Nov, 2020, we are migrating entire setup to CentOS7 using TRAC version1.4.1, SVN 1.7.22 & Python 2.7.
We are facing trouble with Subversion Access panel (getting blank page).

Plugins:
LdapPlugin-0.7.0dev-py2.7.egg
TracAccountManager-0.5.0-py2.7.egg
TracDownloader-0.1-py2.7.egg
TracIncludeMacro-3.2.0dev-py2.7.egg
TracScreenshots-1.2dev-py2.7.egg
TracTags-0.12dev-py2.7.egg
TracUserManagerPlugin-1.2.0dev-py2.7.egg
TracWikinfo-0.2-py2.7.egg
SvnAuthzAdminPlugin-1.0dev-py2.7.egg
