Sounds like something has become mucked up while you've been trying your best to sort the issues initially encountered.... if you just now installed either mod, it might be best to completely uninstall - afterwords you need to install one at a time, testing each this way you sort any issues in the first one installed before installing the second mod and you can then differentiate between the errors from both

Edit: Also no, with BB Codes it starts as [EXAMPLE] and the contents in between i.e.
[EXAMPLE]Code that interacts w/ BB Code to render properly here[/EXAMPLE] so it only needs a ending tag i.e. the / to tell it "Hey we started reading this code now stop reading and show the output on screen" more or less.
