Re: Bug When Deleting Or Modifying Category And Boards

I think it is blocked by ctracker/engines/ct_security.php

try to cut some of code

for example
cut
[code linenumbers=false]'insert%20', 'insert ',
          [/code]

I recomend first to cut all this, leaving '_env'
If it is helped you when try to search the code blocking you
