I have two websites on seemingly identical PHP installations but on two different servers, both MODX 2.8.1. On only one, when I try to set friendly_urls to Yes the manager crashes and I get a white screen. And friendly_urls remains No.
Both have the same .htaccess file.
Have tried uninstalling all plugins. No change.
No new error appears in the log after the white-out.
I can change other friendly url settings (like use_alias_path and automatic_alias) to yes. The white-out only occurs when trying to set friendly_urls to Yes.
Any ideas what needs to be done here to stop the white-outs?
