Hey,

I've noticed these errors come up a lot on our installation as well.  They're pretty harmless, but annoying when you want to find something that's really wrong with your site.  Would you mind submitting it to Trac?

Hi,

thanks for your answer. It is really annoying. Out error_log generates more than 15MB each day. So I will report it on trac.

Best

Hi,

I have similar (or the same?) warnings (like [Wed Sep 08 07:15:44 2010] [error] [client xxx.xx.x.xx] WARNING: 2010-09-08 07:15:44 (CEST): "parse_url(/pg/blog/group:610) [<a href='function.parse-url'>function.parse-url</a>]: Unable to parse URL" in file D:\\web\\htdocs\\engine\\lib\\elgglib.php (line 941)) and as I understood in Version 1.7.5 there is a fix for that. Can I integrate that without upgrading the rest. And if so, which file(s) would that be? Or can I just use the solution mentioned above?

Thanks!

are you thinking to do this in a plugin?

no, I think thats a core feature.

For reference, BvdH was kind enough to report it here: http://trac.elgg.org/ticket/2110
