Empty forum page nad HTTP 500 after upgrade from 2.0.18 (have access to dashboard)

JoosBuijs

Hi all,

I just followed all installation instructions (including deleting the files and uploading the net .htaccess file) for my upgrade from Vanilla forums 2.0.18 to 2.2b1.

However, when I want to access my forum I get an empty page (page source shows it's really empty). I get an HTTP 500 Internal server error in IE. I do have access to my dashboard.

I have followed the instructions from http://docs.vanillaforums.com/developers/troubleshooting/ but I suspect my .htaccess file is the cause. I have enabled the RewriteBase to the correct subfolder (I believe). Is there anything else I can try?

Who is your host? Does it work if you use the old .htaccess ?

Dear Adrian,

Thank you for the swift reply!

My host is a non-commercial one (webserver is installed by IT in our institution).
With their help I was able to find the following error message in the Apache error log:

PHP Fatal error: Call to protected method MessageModel::inCategory() from context '' in /var/www/win/promforum/applications/dashboard/models/class.messagemodel.php on line 184

Since changing 'MessageModel' to 'self' did not work, I made the inCategory function public, and now it seems to work (still need to give it a thorough test run).

Not sure if this is a bug?
The server is running PHP 5.3.3, Apache 2.2.15 and MySQL 5.1.73.

Thnx for the help!

Might really be an issue that needs to be fixed in Vanilla. Line 183-185 of class.messagemodel.php:

$Result = array_filter($Result, function ($Message) use ($CategoryID) {
            return MessageModel::inCategory($CategoryID, val('CategoryID', $Message), val('IncludeSubcategories', $Message));
        });

The closure no longer has access to private or protected members of MessageModel. A solution could be (PHP >=5.4) http://au.php.net/manual/en/closure.bind.php or, as @JoosBuijs suggested, make MessageModel::inCategory() public.

yes this is still an issue with 2.2 and php 5.3 requirement in readme, creating a bug in 2.2

@JoosBuijs nice work around
