Hi Steve,

I have a page with the Repository module. Lately, I receive several event log errors daily that appear to be some European websites trying to add querystring params to my repository page.

Can you shed any light on this?

Thanks for looking at this,
Buck

There are typically two causes for these types of exceptions.

1.) Google or other bots searching for old content, that has such been removed.  (Document or link updated, etc)

2.) Individuals trying to use linkclick to get to content (not typical)

Neither of these items are a risk to your site, simply purge your log and you are fine.
