Hello! I am new to the community and recently started to develop in Plone. I was testing some versions and when I tried to reinstall version 5.2 the following problem appeared:
File "/home/rafa/Plone5.1/buildout-cache/eggs/diazo-1.2.8-py2.7.egg/diazo/rules.py", line 293, in process_rules
rules_doc = etree.parse(rules, parser=rules_parser)

IOError: Error reading file '/++theme++barceloneta/rules.xml': failed to load external entity "/++theme++barceloneta/rules.xml"
Plone can run on my computer, but I can't edit anything anymore. The interface also got a little unconfigured.
I would like to know what may have caused this problem and how I can solve it. I am trying to fix it for days but this problem persists and I cannot continue my studies in Plone. I've tried to install other versions but nothing worked.
If anyone can help me, I would be grateful. And if you can, have a little patience with me, I'm a newbie.
