Fixes Needed for 2.5

We migrated our entire Joomla site from 1.5 to 2.5, and since then have been experiencing a few, specific problems related to MyBlog and Sh404SEF. We are looking for someone who can fix these for us. The problems are quite simple: Myblog problems: - This component' clock is 5 hours ahead (it seems to be using the server time). The Joomla time is set correctly and the time in all other components is correct. - Some users who should be able to create articles from backend are unable to do so/editor won't load and error message is given. Sh404SEF - Front-end editing is not functioning. When hitting Save or Cancel after front-end article editing, we receive an "invalid task" error. When Sh404SEF is turned off, it seems to work correctly. This is true in multiple templates.
