joomla - MyBlog expert needed

I get the following error when going to extensions - myblog : Fatal error: Allowed memory size of 67108864 bytes exhausted (tried to allocate 20752008 bytes) in /home/familieh/public_html/libraries/phputf8/mbstring/[login to view URL] on line 30 You know what this is, and can fix it fast? There also is some other problems with MyBlog. I think this is related to windows 7, have you seen this before and know what im talking about? The blog html code is not right. THere is no paragraphs.. I think im not the first one to get this problems. Read the above, im not interested in design experts and bidders that can create great stuff. i need to fix the issues adressed above. You should tell me in PM that you have seen this issues earlier, or the bid will be trashed.
