I have installed 3.01 and it's running fine on my local server. However, on the live server there is one problem: clicking on any category results in a blank page with the plain text words “[color=#000000][font=Courier]Error_occurred[/font][/color][color=#000000][font=Courier]” in the upper left corner. [/font][/color][color=#000000][font=Courier]Has anyone encountered anything like this? What is the fix? [/font][/color]
[color=#000000][font=Courier]I really do not want to have to do a complete reinstall especially without knowing if that will even fix the problem.[/font][/color]
See Administration → Logs
and search for recent records (I guess the Type must be “database”)
I have similar problem with CS-Cart 3.0.3.
[color=#282828][font=arial, verdana, tahoma, sans-serif]Administration → Logs no have any records about this.[/font][/color]
[color=#282828][font=arial, verdana, tahoma, sans-serif]For example: i clear logs, then i try open any category → «[/font][/color]Error_occurred», see CMS log, and log empty 
.
