PWB dropped support for Python2 in its master branch few weeks ago.
Many bots still rely on Python2, and the ones using latest version from /shared/pywikbiot/core have started to raise fatal errors few days ago.
A Python2 version of the lib was published at /data/project/pywikibot/public_html/core_python2
To give easy access to this version for bot owners, please create /shared/pywikibot/core_old_python2 -> /data/project/pywikibot/public_html/core_python2 simlink, and update README file.
For record, here are current pywikibot symlinks:
