Situation
after I submit for example, a the privacy form or any questionnaire, I try to review it from the admin/physician side. But when i do that, I encounter an error
OpenEMR Version
openemr 7.02 on aws, cloud express plus
Browser:
chrome/brave
Operating System
mac os
image for example:

I thought it was an aws problem, so but the same problem is also on the demos of openemr.
I changed some permissions on the serializer. ran these commands in the /HTMLPurifier/DefinitionCache
chown -R apache:apache Serializer
chmod -R 755 Serializer
and now I can somewhat review these documents.
Can I know why the issue where I can’t review the documents exist and if the changes I made will cause any security issues? Also, any alternative better solutions you can refer me to would be appreciated
