My company is still running a ~12 year old CMS for project management and until yesterday it was working fine.
Then I uploaded a version of Tiki Wiki CMS to complete separate folder on the same server.
That somehow triggered the old CMS to partially break down. Some functions involving stings stopped working altogether. I also noticed that suddenly special characters were not displayed correctly anymore so I guess it’s a charset issue.
So I am a bit puzzled how this could have happened.
Could the .htaccess files from the Tiki Wiki CMS somehow affect the global charset settings? I checked the local phpinfo in the old CMS directory but nothing was changed.
