Print link and RSS links giving 500 errors all or a sudden

I am wondering if you have any idea what could be causing my Print links below the EasyBlog toolbar and my RSS icon in the EasyBlog toolbar to have stopped working. They now give 500 errors.

Here is an example of a page with the problem (I think all the pages now have this problem, or at least most of them):

Could you please look at a page and let me know if anything jumps out at you?

My host said it was caused by the template but I switched the template and that did not fix anything. These are the urls that are not resolving in case this helps. Maybe they are not formed properly?

Interestingly enough I did find some pages with links in them that did work properly. Here is an example:

https://www.drcarney.com/blog/entry/take-the-new-year-health-challenge

Working link:
https://www.drcarney.com/blog/entry/take-the-new-year-health-challenge?tmpl=component&;print=1&format=print

Do you think we might be running up against a characters limitation built into Joomla? Or possibly something built into EasyBlog?

I sure would like to resolve this. :-) Google Webmaster Tools sent me a notification about all the broken links that have appeared on the site.

Any ideas you have will be greatly appreciated.
