Plugin broken and breaking backend after domain move

  1. I moved a site from one domain to another. Everything worked fine, except for the gravity forms plugin. Here is what I did.

    At first nothing was working and I removed all the plugins from the plugin folder and then it fixed everything. I moved the plugins back one at a time to see if they were the issue. Only gravity forms was.

    I have only 2 other plugins activated. And even when I deactivate or remove them, when I go to install gravity forms, it makes the backend of the site white?

    I've renamed, deleted and re-installed and nothing changes.

    Any ideas?

  2. If you have access to the old installation, the easiest thing to do is export the forms, then import them into the new site.

    If you do not have access to the original site, you can try the meta recovery tool. You can download that from the bottom of this page: http://www.gravityhelp.com/downloads/#gf_footer_menu

    Install and activate that, then under the Forms menu, find the Meta Recovery option, and then select the forms you want to try and recover. If that works, you'll be good to go.

    If not, you might need to recreate the forms. Or, switch the domain name back and then export your forms and start over changing the domain name.

    This happens because Gravity Forms stores the domain name in some places as a serialized value. When you change the domain name, you normally change its length (i.e. google.com is 10 characters while ask.com is 7) and that destroys the reference for the serialized value (the serialized string includes the length of each individual string.)

  3. The problem is that when I activate the plugin, it turns the whole backend to a white, blank screen. I can't seen anything. The only way to get the page back is to delete or rename the plugin.

  4. Sorry, I completely confused two different topics. The advice I gave does not apply to your situation.

    If the screen is white, it is because you have a 500 Internal Server Error. That error will be logged somewhere. We need to know what that error is so we can find out what is causing the white screen. Do you have access to error logs or can you contact your host?

    Are you sure the new host meets the minimum requirements (bottom right of this page)?

  5. The host meets the minimum requirements.

    I do have access to an error log. I don't know what do to with it. Can I email it to you?

  6. Please post the relevant portion to someplace like pastebin.com or pastie.org. Just the log entries from the time after you started experiencing the problem with the blank screen. If you would like to save the log to a file and upload that to something like dropbox or your server, that's OK too. Just post the link here so we can download the log. Thank you.

  7. Here is a link to the error log.

    We had a redirect on the .htaccess file that I thought might be causing some issues, but I removed that and it still isn't working.
