Question Fatal error - clean new installation - MySQLi database

I'm not sure how to trace down this "fatal error" that I suddenly got going.

• I have 2 web sites running on the same server. On one of them, the install went very easily. On the other, I'm having issues.
• Using the "install from web" feature from Joomla, the install fails, saying: "Sorry, installation failed on fatal error."
• Under "installation details" it says only: "Prepare installation... OK"
• The tail on the Apache error log says:

• I checked permissions, all of the files are owned by the web process.
• I checked the .htaccess file, which is the original issued by Joomla without alterations in their htaccess.txt.
• In php.ini the settings clearly exceed the minimum technical requirements listed in the documentation.
• In the Apache site file, all settings between the two sites are identical.
• The server is a fresh install, as of this week, and the Joomla install is fresh as of 10 minutes before installing Kunena.
• I am installing from the superuser account on Joomla!

If there is any further information desired (config options, etc.), please let me know.

Also: it looks like the SQL is not being executed, and I'm not sure why.

The install uses MySQLi and the permissions there are everything but 'grant'.

Hello,

Is-it a clean install or an upgrade from a previous version ? If yes from which one ?

You have missing files or the plugin kunena system isn't enabled or installed.

As I wrote in the first post:

It's a clean install.

Try to unzip kunena package that you have downloaded and install in first kunena plugin sytem, check after that is right enabled.
Then install lib_kunena package, then kunena_media package and you can install the two remaining package.

Try to unzip kunena package that you have downloaded and install in first kunena plugin sytem, check after that is right enabled.

You can check this first: screencast.com/t/Jcth0a8t

I have never tried to install Kunena on a MySQLi database. You may find the following information is also useful: Technical Requirements - MySQL requirements

can you create a superadmin account for me. then i will check the issue.

Check if you have Kunena - System plugin enabled and try to disable it. It will be automatically enabled again after the installation. If that doesn't work, try to enable the plugin and try again.

Okay: RESOLVED.

There were multiple issues:

• There was originally a misconfiguration in the php.ini file, the upload size was not high enough (1M) to accommodate the upload.
• There was a residual file left over after the first failure, and an automated security script on my server changed the permissions on that whole directory when I logged out. (I had previously assumed the permissions were correct, since I hadn't changed them myself and didn't know about the security script running in the background.)
• The Kunena package was corrupted by a change in permissions mid-operation, but still passed a basic CRC check, though it failed the MD5 hash check. Again, the security script appears to have been at fault.
• The Joomla! platform did not remove the failed package.

The fault was not with Kunena, though it failed with Kunena for obvious reasons, as stated above.

STEPS TAKEN TO RESOLVE:

1. Manually cleared the cache in Joomla! CMS.
2. Manually located and removed the corrupted file and all traces of Kunena.
3. Double-checked the settings to ensure compliance with both Joomla and Kunena.
4. Uploaded Kunena.
5. SUCCESS!
6. Configured Kunena.

Thanks, all, for the feedback. Though none of it directly resolved the issue, it sparked enough thought that I began thinking in different ways about it.

EDIT: Also, remembering to double-check and triple-check things meant that I was repeating a lot of work, but continuing to find issues. Ultimately, the issues seemed related to my server's configuration, more than anything else.
