I'm having an issue Installing OE. I get all way through to Installing the "Install Profile" page which completes, and then I get this:

An AJAX HTTP error occurred. HTTP Result Code: 500 Debugging information follows. Path: http://opentest.byethost12.com/install.php?profile=openenterprise&locale... StatusText: Internal Server Error ResponseText:

Attached is a link to the screen shot.


Any Idea's on what I'm doing wrong? I have tried to Reinstall, and I get the same result. I have tried finding ways to fix this online, but have had no luck.

Thanks in advanced for all your time and help!

Hi Maurermr, I had the same problem on bluehost.

Check the error logs. For me it was a memory problem. You will need to start with a fresh db and re-reinstall Open Enterprise. Before the install though, you will need to increase your memory_limit (php.ini).

Let me know if this helped!

Version: » 7.x-1.0-rc2

I had a similar problem installing Drupal Open Enterprise locally (although with version 7.x-1.0-rc2).

I found this recommendation:
Installing Drupal at Host1Free: "An AJAX HTTP error occurred"

Following these instructions, I added the following line to the end of my .htaccess file:
php_value auto_append_file none

When restarting installation from scratch, it completed successfully.

Further to above, you could also try the following prior to installation of OE:

1. In your .htaccess file, in addition to the line mentioned above...
php_value auto_append_file none

...also add another line to increase the PHP memory limit...
php_value memory_limit 128M

2. Ensure permissions are set correctly on your sites/default/settings.php and sites/default folder. Once you've downloaded and extracted OE, go to the command line, browse to the folder where you extracted Drupal and enter:

$ cp sites/default/default.settings.php sites/default/settings.php
$ chmod a+w sites/default/settings.php
$ chmod a+w sites/default

Ensuring all these things were done before installation seemed to help when installing locally, although I'm not sure it's necessary to do this before all installations depending on the server set up in each case.

Hope it helps.

We add php_value auto_append_file none and php_value memory_limit 128M to the end of .htaccess (found in the root of the OE distribution folder)? After i add there 2 lines, I cannot even proceed, as there is error as shown below

Internal Server Error

The server encountered an internal error or misconfiguration and was unable to complete your request.

Please contact the server administrator, webmaster@XXXXXXXX and inform them of the time the error occurred, and anything you might have done that may have caused the error.

More information about this error may be available in the server error log.

Additionally, a 500 Internal Server Error error was encountered while trying to use an ErrorDocument to handle the request.

Hi aniceguy,

Yes, the .htaccess file found in the root of the OE distribution folder.

I actually found that I was able to get away without adding the php_value auto_append_file none line in the end - so I only added the php_value memory_limit 128M which when reinstalling from scratch did the job.

Are you installing locally or to a remote server? Are you able to get access to your phpInfo to see your existing PHP memory limit? If installing locally, have you tried restarting Apache? Also, are you editing the .htaccess file to up the memory limit, wiping the database and then reinstalling?

Just to summarise what I did and how I ended up getting it to successfully complete install of OE...

  1. Restarted Apache / MySQL
  2. Removed any existing database from prior unsuccessful installations of OE and recreated, ensuring my user had full access to new database
  3. Got a fresh download of OE 7.x-1.0-rc2 and extracted
  4. Edited .htaccess file to add php_value memory_limit 128M line to the end (prior to this my memory limit was set to 32M)
  5. Made a copy of sites/default/default.settings.php to sites/default/settings.php; ensured permissions were set correctly on sites/default/settings.php and sites/default (see above)
  6. Visited the site URL to run the install from scratch

Hi mwolfindale,

Thanks for the concise detailed step.
Actually, i stuck at your step no. 4, where i need to Edited .htaccess file to add php_value memory_limit 128M line to the end (prior to this my memory limit was set to 32M).

I keep getting the error that I described in previous post. It seems that we cannot just add php_value memory_limit 128M line to the end of the file, seems to make it an invalid content structure?

Can I confirm that before editing the .htaccess file, the last few lines are actually as shown below?

 # Serve correct content types, and prevent mod_deflate double gzip.
    RewriteRule \.css\.gz$ - [T=text/css,E=no-gzip:1]
    RewriteRule \.js\.gz$ - [T=text/javascript,E=no-gzip:1]

    <FilesMatch "(\.js\.gz|\.css\.gz)$">
      # Serve correct encoding type.
      Header set Content-Encoding gzip
      # Force proxies to cache gzipped & non-gzipped css/js files separately.
      Header append Vary Accept-Encoding

 php_value memory_limit 128M <--This line is added by me, as per your instruction.

Hi aniceguy,

Sorry forgot to ask before if you're installing locally or to an external server?

If the latter, could be a case of contacting your hosting company to make sure you've permission to override default values?

I followed the instructions about php mem limit 128 and php_value auto_append_file none but still get the same error everytime, exactly the same from the first post... Any other ideas?
Thank you
It is installed in my own computer... fresh install... checked php.ini and mem limit is 128...
