Subject Re: Gerald: please update module to include patch for 3.38+
Date Sun, 20 Sep 2009 14:45:23 GMT
Hi Gerald,

Thanks for the advice.

What I may do is try to install again from scratch on Centos 5 and
show you my errors as I go.  That is, of course if you are OK with
this!  There seems to be a lot of virtual dedicated server companies
offering Centos 5 with Plesk so I am sure others would benefit.

Great you're back!  Really looking forward to your latest offerings too.

Maybe the community could get together and get some sort of forum/site
going where we can all talk about our projects and problems?  I am
happy to offer hosting for this.
