500 Internal Server Error
The request was not completed. The server met an unexpected condition.
my_ip_address/~my_username/joomla/ (port 80)
Please forward this error screen to my_ip_address's WebMaster.
Apache Server at my_ip_address Port 80
In the quote above, I replaced the real ip address with "my_ip_address" and the real username with "my_username" to protect my identity. The entire site is placed under the "joomla" directory.
I can, however, access the back end administrator as usual.
I ran a test by inserting some individual HTML file in the "joomla" directory and try to view it through the link "my_ip_address/~my_username/joomla/testfile.html" and it works. It seems like only the files that belong to Joomla in the front end are inaccessible. All these files belong to a joomla site that has been running for a year in another server.
Does anybody have any idea why I got this error?
