like I already stated on another plugins page:
I am still wondering why a lot of plugins break because of this small change I have. And installing into a folder, I found on the wordpress codex. There are even installation instructions for installing into a subfolder: http://codex.wordpress.org/Installing_WordPress#In_a_Subdirectory
If I had known this would cause me so much trouble, Iâ€d avoided it long ago.
I guess its just something like get_bloginfo(â€™wpurlâ€™) instead of get_bloginfo(‘siteurl’) right?
