I am continuously getting this error- 500 Internal server error on my Joomla 1.5 website.
Found solution 1-My folder permissions are 755 and files are 644 (even getting the same error with 755). >>>Not working :(
Found Solution 2-.htaccess related error. >>>There is no .htaccess at all, still site was running fine for last two years.
Error log says (file at the rrot of my site)- "PHP Fatal error: [Zend Guard Loader] Extension "Zend Guard Loader" cannot be loaded twice in Unknown on line 0".
The error log from Cpanel root says- "Permission denied: [client IP:PORT] AH00529: /home/mysite/public_html/administrator/.htaccess pcfg_openfile: unable to check htaccess file, ensure it is readable and that '/home/mysite/public_html/administrator/' is executable".
Can't proceed with this error for quite a long duration (for 6 to 7 days).
An immediate help will be highly appreciated.
