I am attempting to evaluate Vanilla. Yesterday I installed Version 0.9.2.6 without incident. Everything worked fine.
When I saw that some of the new extensions require Version 1.0, I decided to install that. Since I am still in the evaluation stage I decided to simply do a full install of 1.0, rather than an upgrade. I created a new folder. Uploaded the software. And tried to run installer.php. I get the first page, but when I press enter to proceed to the second page the system hangs and I get a blank HTML page back.
When I view the source of the HTML page I find this -
The following error occurred: [code=CANT_CONNECT] Could not connect because of networking problems. Contact your system administrator.
Strange that 0.9.2.6 installs cleanly on my server. 1.0 does not. I never get to the point in the installer where I can enter my server and database information. Nothing.
I am hosted thru Host Excellence. My information is as follows.
Hmm. It's happened before that people get a blank page after setting up mysql details, but not after step 1...It cant even be a php5 issue this time. I wonder if it's an IIS or permissions thing *scratches head
Well, step 1 checks file permissions, so it must be something to do with that.
Vanilla 0.9.2.6 and Vanilla 1 are very VERY different applications. The first step in Vanilla 0.9.2.6 just checked permissions, but the first step in Vanilla 1 actually creates configuration files on your server. It is likely something to do with that.
The installer has a lot of debugging stuff thrown in there so that you get verbose error messages, but whoever configured your server has the power to override inline php configuration settings and make it so that errors don't get treated properly and instead you get strange things like a blank page. Some hosting companies will do this so that even if there are errors in applications, their customers won't see them and therefore they won't get as many support requests. Other companies do it because they just don't know any better.
Either way, the only way to figure out what's going wrong is to go into the file and add echo('test');. Then run the script and see if it echos. Then keep moving that echo statement down in the file until it stops coming out. That way you can identify which line actually causes the script to hault. My guess is that it will be somewhere between line 127 and 165.
Tagging on here, but I can't get past stage 1 - and yes it is a new installation, not an upgrade.
Getting this problem:
"Vanilla seems to have been installed already. You will need to remove the conf/settings.php, conf/database.php files, and all database tables in order to run the installer utility again."
I keep removing these files (there is no database created) and having another go, but it produces the same result? MySQL 4.1.15
EDIT: now getting -
Precondition Failed
The precondition on the request for the URL /PMS-Forum/setup/installer.php evaluated to false.
If you’re seeing a lot of “Error 412: precondition failed” errors, it’s most likely the result of something triggering a rule in mod_security. TextDrive uses mod_security to block comment and referrer spam, but sometimes it get’s triggered by mistake. This can happen if something on your site (like a URL) matches a common pattern (like ”-poker”, ”-pictures”, or ”-sex”).
A quick way to resolve this is to put the following in a .htaccess file in your public or public_html directory:SecFilterEngine Off
Inserted that and cleaned out the newly created conf/settings.php and conf/database.php files and bingo all go now.There must be something in Vanilla triggering this with TextDrive, as the rest of what constitutes this site was OK, but now mod_security is disabled I am no longer protected from referrer and comment spam... so I'll have to troubleshoot - as they say!
Thanks for pointing me in the right direction Mark.
