(adjust based on where you’ve install RT on your filesystem obviously). You can check what configuration RT has loaded by going to Admin->Tools->System Configuration as an admin user.
Also note from the RT documentation that “This option can be overridden by users in their preferences.”
I cleared mason cache and restarted all of my services but still it doesn’t work.
I also rebooted my server and nothing happend.
I checked my preferences for maximum inline body and it was set to default. do you have any idea what is happening?
Sounds like you’re editing the wrong file then. For example are you editing the default RT_SiteConfig.pm but have a copy in your local files that is overriding it?
if I change MaxInlineBody to something like 4000000 or 300000 nothing will happen. again my MaxInlineBody parameter in Admin->Tools->System Configuration is set to default.
Look in Admin->Tools->System Configuration as it tells you there on the right hand side of each configuration item. On ours it either says “core config” or “site config” depending whether we’ve overridden the distributed config for each item or not.
The section called RT core variables also has a subsection called Loaded config files that shows you the explicit absolute paths of the config files that RT has loaded. If you’re editing a file that isn’t in that list, that would explain why your not seeing any changes being made.
