Unable to access parts of theme

Hello I’m new to wordpress, using it installed on a free server, and I’m having a problem with the theme. Whereas the header and colors come up fine, the bottom half does not show up at all, and I get the error:

Warning: include(): Unable to access /www/99k.org/m/u/s/musikfreek/htdocs/wp-content/themes/musicifyourlifestyle/lsidebar.php in /www/99k.org/m/u/s/musikfreek/htdocs/wp-content/themes/musicifyourlifestyle/index.php on line 2 Warning: include(/www/99k.org/m/u/s/musikfreek/htdocs/wp-content/themes/musicifyourlifestyle/lsidebar.php): failed to open stream: No such file or directory in /www/99k.org/m/u/s/musikfreek/htdocs/wp-content/themes/musicifyourlifestyle/index.php on line 2 Warning: include(): Failed opening ‘/www/99k.org/m/u/s/musikfreek/htdocs/wp-content/themes/musicifyourlifestyle/lsidebar.php’ for inclusion (include_path=’.:/usr/lib/php’) in /www/99k.org/m/u/s/musikfreek/htdocs/wp-content/themes/musicifyourlifestyle/index.php on line 2

Fatal error: Call to undefined function gzinflate() in /www/99k.org/m/u/s/musikfreek/htdocs/wp-content/themes/musicifyourlifestyle/footer.php on line 1

The theme is uploaded in its entirety correctly, and the only problem that I can see is it seems to be trying to get the pages from 99k.org instead of musikfreek.99k.org (the 99k.org subdomain is default with the webhost).

Under settings>misc I changed the full url path to files to “https://musikfreek.99k.org/wp-content/” but it didn’t make a difference. How do I fix this?
