Playing with Joomla

I've been having trouble with access to my Home page and Blog page of my website for a while.  Every now and then it wouldn't open but my other pages were okay.  The common denominator was a twitter plugin I had installed into Joomla a while ago.  I've now removed this and added another, which seems better.  Fingers crossed it won't cause any problems.  Let me know if you have trouble opening up my website :)
