Installing YABB via WHM Cpaddons produces weird .PL error

There is a name I have not heard in a long, long time! .... YaBB!

YaBB was completely banned across many hosting networks for very serious and unresolvable security problems and then if that was not bad enough also suffered from some bad programming issues that effected the performance of the entire server on many web hosting servers.

YaBB ultimately disappeared from the hosting scene except for a few sparse remnants here and there and the past few years I really have not seen any active mention of it anymore.

In light of the above and first hand knowing YaBB's darker history, I would strongly advise you recommending to your client that they choose some other forum application software. A very good pick would be phpBB which actually has converters available to convert an existing YaBB community or database on over to phpBB. There are several other good choices as well.

Now regarding your support question though ....

It sounds like your web server might not be configured to recognize Perl scripts (with the .pl extension) or maybe don't have mod_perl. Although it could also be a permission issue as well. A lot would depend on specifically how your server is configured and I would probably need to know more details to be able to tell you more specifically what is going on.

You could try manually installing it which might give you a little better control with the installation anyway.

As I said though, you really should look at installing something else as YaBB is really not known to be so good.

 

Based on what you said, I suspect if you go into packages and check the account plan for the client, you'll find that the "CGI Access" box is unchecked which is what would trigger having the RemoveHandler added.

Aside from packages, this option also appears under individual accounts
under the option "Modify an Account" in WHM.
