We've been running Hesk (licensed) for several years with no trouble whatsoever. I originally had it running on SuSe Linux, and eventually moved it to newer hardware running CentOS 6.3. We were fully upgraded to Hesk 255.

That server died this morning. I had extra server hardware available, so I've started a fresh install of CentOS 6.3 and have that up and running with PHP and MySQL both running.

In 3 previous Hesk installs I've followed the exact same procedure as I am now and I've never had a problem. This time, when I open the /hesk/install URL on our internal web server, I get:

Forbidden
You don't have permission to access /hesk/install on this server

For this install, as I've always done, I created a folder called "hesk" in /var/www/html. That folder that I created myself does not get the error. The hesk files were put directly into that folder so that on the server, the install folder is at:

/var/www/html/hesk/install

So I tried changing permissions on the install folder to match the parent folder (allowing "access files" to all groups). When I do this, I no longer get the error; instead I just get a 100% blank white web page. No install script, no text, no anything. Just a plain white page. Again, I'm following the same procedure I've always followed for installing or upgrading Hesk, and this has never happened.

I've verified that the MySQL service is running, and the default root apache page loads fine, as do any test html pages that I've placed into the same directories to make sure httpd is functioning correctly.

I'm not sure what to try next.

EDIT: The only thing different this time is that I'm installing the full version of 255. My previous installation was the full version of 252 that was upgraded to 255.

Your server logs should give more details as it seems a server-side error.

However, one thing to check is can you open index.php directly, for example:
/hesk/install/index.php

I tried opening /hesk/install/index.php with the same result (this is with Firefox). I just tried in IE and instead of a blank page, I get a 500 Internal Server error with the following text:

The website cannot display the page

Most likely causes:
•The website is under maintenance.
•The website has a programming error.

The root site is still working with the default Apache page in both browsers.

I will check the logs and update with that info as soon as I can.

Ok, I got the initial problem sorted out.

For some reason, my USB drive was removing ALL file permissions from the folders when they were being copied to the "hesk" folder on my server.

I deleted everything and unzipped the Hesk files directly into the "hesk" folder and tried again.

It is working now. Except that I'm getting an access denied error for the default MySQL connection that I installed, but that is a different issue, so I'm off to get that resolved.
