Hi…

I am upgrading a 1.6.8 version of EE to 2.1.3. Everything seemed to go okay. Most areas of the control panel not dependent on 3rd Party code are working. But when I go to the site, I get the error “Site Error: Unable to Load Site Preferences; Invalid Preference Data”.

I can easily roll back to 1.6.8, but I’m not sure what I would do differently if I did. Any thoughts?

Also, if you recommend I first upgrade to 1.7, can you tell me where I can find the EECore file for that build? I was going to try to do that, but I can’t access it from my account… only the newest 2.1.3 version.

Thanks!

Hi Gusto,

Since you were on EE Core, I assume you had only one site (no MSM installed) correct? Can you clear all caches and see if that helps?

Hi Brandon,

Yes, just a single site install without MSM.

The cache clearing didn’t do it. By the way, here are my system details:
CentOS 5.5
PHP 5.1.6
MySQL 5.0.77
Apache 2.2.3

I did a few hours reading on the forums. It seems this error relates to database issues. I have been running EE 1.6.7 for ages. When I began the update to 2.1 process, one of my 3rd party plugins required me to have at least 1.6.8 before I could update it. So I made this change, updated the plugin (and a second plugin) and then went ahead with the 2.1 move.

I can roll back to 1.6.8 or I still have 1.6.7 live on my current server. Let me know what direction you think would be best to take.

Hi, Gusto.

Let’s have you run the EE2.x Server Wizard just to make sure your settings support EE2.x.

Also, go ahead and roll back to 1.6.8, then upgrade to 1.7.0.

See:
http://eebeginners.com/index.php/begin/articles/howto-download-1.x-version-of-ee

Backup your database again after making sure 1.7.0 is working as expected.

Are you doing this on a live site, or on a development server?

I didn’t see that link down there Sue… thanks!

My overall plan is to move our site to a new server. At this point, I have decided to simply move our current working 1.6.7 site to the server so I can get it up there ASAP. Next, I’m going to duplicate that system on a box here in my office and try the EE 2.1 upgrade again. I likely won’t get to the nitty gritty of this until next week, so put this support request on hold. I think I’ll likely be back with the same issue, but I’m going to increment from 1.6.7 -> 1.6.8 -> 1.7 -> 2.1.3 and see how it goes. I’m also going to run some db fixes while I’m in the 1.x environment and make sure I don’t have any anomalies there.

Sounds good to me.. when you’re ready to work on this again, just reply and it will put this thread back into the queue. Otherwise, don’t reply and it will sit dormant until you’re ready to continue.

Hi again… I’m finally getting to this project and would like to reactivate this thread. At this point I had a working EE installation on my dev server. I ran the update for 1.7. All seems to be fine except I can no longer get to the modules page on my EE Control Panel. When I click the tab I get the following error: “Unable to lead the following language file: lang.forum_cp.php.

I assume this is a language file for the forum module. However I have never purchased or used the forum option in EE. Any idea why the upgrade from 1.6.7 to 1.7 would trigger this? I don’t want to go any further on the path to 2.1 until I get this resolved.

I did check my language/english directory and this file is not in the directory. I also checked my current live 1.6.7 installation and the file is not there either.

Thanks!

Let’s have you look in your config.php file - is there something in there about the forum being installed?

$conf['forum_installed'] = "y";

If there is, change y to n.

No Sue… that config statement isn’t in there at all.

Hi Gusto,

Can you tell us what add-ons you have currently installed?

Just out of curiosity if you add this to your config.php file is there a change?

$conf['forum_installed'] = "n";

Hi John,

Sadly the adding the forum config did not do the trick. Here’s what’s installed:

Hey Gusto,

First, make sure you’ve got a solid backup of your files and database.

Can you try globally disabling extensions and then see if your modules page still gives you the language error? That’s the first, quick step in troubleshooting this. If that doesn’t work, keep extensions globally disabled and then slowly uninstall each module until that error goes away. That should help you narrow down which add-on is erroneously calling the forum language file.

Remember, before you do anything, make sure you have a solid backup! Uninstalling modules will remove data from your EE installation, so you absolutely will need to restore your database.

Hi Kevin,

I already tried globally disabling extensions, but no luck. This is a development server and I have complete backups as it mirrors my live server. So we can do whatever is required. However as I cannot get to the Modules page on the control panel, what is the best was to uninstall each module? Just remove them from the modules directory? (Hope this isn’t a stupid question!  😉 )

Hmm… the only way I can get this error to come up is by adding a folder named ‘forum’ to my ./system/modules folder in EE 1. When that folder is there, the system will look for its corresponding language file.

Even though you’ve never installed the forum module, do you happen to have a ./system/modules/forum folder?

Ok Kevin… you have figured something out… but I still have a bit of a mystery.

First you are right. Somehow a “forum” folder did get placed in my modules directory. I assume the upgrade script from 1.6.7 to 1.7 did this. I removed the folder and then got a “mailing_list” language file error. So I checked that out and discovered a new mystery directory in modules called “mailing_list”. I also still had my other directory called “mailinglist”. So I deleted “mailing_list” and then when on to the next error—another language error for “statistics”. Again a new directory has appeared called “statistics”. I still have my old “stats” directory as well. I deleted “statistics” and now, at long last, I can get to the modules page.

I have checked and my mailing list functions still seem fine. I really don’t use statistics, but all seems well there also. Any idea where these directories came from? Am I okay to delete them? I just don’t want to have any issues as I move forward to 2.1.

Thanks for your help!
