[Plugin: Contact Form 7 to Database Extension] Problems after activation

Maybe another plugin is conflicting.
Look on the Admin – Plugins – menu.
Temporarily Disable (not uninstall) all your other plugins.
Does it work now? If yes, Activate the plugins one by one to determine
which one conflicts. Which plugin was causing it?

—————–

It could be the theme you are using is causing it…
Do this as a test:
In Admin, click on Appearance, Themes.
Temporarily change your theme to the “WordPress Default” theme, or “Twenty Ten” (default for WP 3.0).
It does not cause any harm to temporarily change the theme and change back.
Does it work properly now?
If it does then the theme you are using is the cause.

Was this any help?

Recent updates to the plugin may have fixed your issue. Update the plugin and try again.

Thanks for all your help.

With my existing plugin set active, the latest version of Contact Form 7 to Database Extension allowed some admin pages to load but not any that related to plugins.

The problem turns out to be a conflict with the plugin WP-DBManager, which is an excellent tool for backing up and restoring the database, dropping tables, etc.

For some obscure reason probably related to the lateness of the hour, I missed it the first time around when I worked through my plugins to see if there was a conflict.

I would be very interested in whether you think the problem is in Contact Form 7 to Database Extension or WP-DBManager. If it is in WP-DBManager, is there any way to identify where it is affecting Contact Form 7 to Database Extension so I can provide as much detail to the author as possible?

Again, many thanks for your help so far.

I’m glad you were able to chase this down.

I have one quick thing to try/rule-out:

The newer 1.6.x version of my plugin are now including Javascript from the DataTables project. It is worthwhile to go through the quick experiment of turning this off in my plugin and seeing if that makes any difference.

1. Be sure you have the latest version of my plugin.

2. Point your browser to URL https://<your-site>/wp-admin/admin.php?page=CF7DBPluginSettings (hopefully things aren’t so messed up that you can’t get to this page)

3. On that page, set Use Javascript-enabled tables in Admin Database page to false.

4. See if the conflict resolves.

I’ll see if I can schedule some time to install WP-DBManager and see what I can figure out.

Sorry but that didn’t work.

I also tried deactivating all plugins except Contact Form 7 to Database Extension and Fast Secure Contact Form, making the change you suggested, and then activating the other plugins.

All I’m getting from the URL you suggested and from any of the pages under the Plugins heading in the admin page is an empty page (empty as in no html beyond the barest header and body tags as well as empty as in blank).

I really appreciate your efforts and it would be great if you had the opportunity to see what is happening with WP-DBManager.

When you have a white page, there could be a PHP error on the page. Your server might have PHP error display turned off so it does not show what the error says, that is why the white page.
Do you have PHP error logs? Look and see what the error says.
You can also try this temporarily to possibly see the error.

Edit the wp-config.php file and add this line:
define('WP_DEBUG', true);

Be sure to remove it later when done testing as some poorly written
plugins and themes will display warnings that are not really hard errors just warnings.

Problem solved.

I can’t thank you enough. My PHP skills are so rudimentary (read non-existent) that this didn’t occur to me even though I now remember coming across a similar issue with Drupal.

It turns out that the default PHP memory_limit on Rackspace is only 32M and the combination of Contact Form 7 to Database Extension and WP-DBManager (along with everything else going on) was enough to exhaust the available memory.

Upping the memory_limit value to 64M solved the problem.

In case anyone else comes across this, like most hosting companies, Rackspace doesn’t allow access to the global php.ini for your VM. However, it does allow some parameters to be changed using a .htaccess file in root.

Again, many thanks for your patience and knowledge.
