Hy everyone
Some time ago I put an addon to my store(ZenTagCloud)

http://www.zen-cart.com/forum/showthread.php?t=68671

I've uploaded the includes folder, as fare no problems . But ten I
"Copy the code from 'ztc_pagecode.php' to one of the Defined Pages using: Tools -> Defined Pages Editor -> page_4.php"

Since then , my site went ofline

Maybe I also overrided the tpl_index_default.php page

How can I restore these?

my admin login also tells me:

Warning: error_log(/home/a8033afr/public_html/cache/page_parse_time.log) [function.error-log]: failed to open stream: No such file or directory in /home/a8033afr/public_html/admin/includes/classes/logger.php on line 60
Parse Time: 0.718s
What does this mean?

thx in advance
