Thanks you guys this is really helping; soon I'll be an expert

someday. But I ;ike Serendipity, I hope to upgrade, but I'm going to wait a little. I guess I have a problem with some permissions somewhere.
I tried installing the Extended Media plugin, I lightened up some permissions somewhere, I didn't think it would hurt, I changed some 5's to 7's, I have to check back; before I knew I was finished, I started messing with the Spartacus plugin; from the Serendipity Administration Suite(SAS): I check the Spartacus Box, and then I click "click here to intall new plugin" and get this error:
Trying to open URL package_event_en.xml...
Permission denied
Notice: Permission denied in /home/u1/charlesrkiss/charlesblog/html/bundled-libs/PEAR.php on line 848
Permission denied
Also, when adding a weblink to my blog from the SAS "entry", I click "SAVE" , and I get this error:
• Checking

Permission denied
Notice: Permission denied in /home/u1/charlesrkiss/charlesblog/html/bundled-libs/PEAR.php on line 848
Permission denied
line 848 in PEAR.php is:
847 if ($this->mode & PEAR_ERROR_TRIGGER) {
848 trigger_error($this->getMessage(), $this->level);
Seriously, thanks again, I'll continue to work on it!
