Title: New Version 3.1 Not Working Last modified: August 24, 2016 --- # New Version 3.1 Not Working * Resolved [ternion](https://wordpress.org/support/users/ternion/) * (@ternion) * [11 years ago](https://wordpress.org/support/topic/new-version-31-not-working/) * Just upgraded to version 3.1 of the plugin and the admin screen for the plugin has a blank page. I have changed permissions on the cache folder, but still have a blank admin page. * Please advise. * Robert * [https://wordpress.org/plugins/wp-mobile-detector/](https://wordpress.org/plugins/wp-mobile-detector/) Viewing 12 replies - 1 through 12 (of 12 total) * Thread Starter [ternion](https://wordpress.org/support/users/ternion/) * (@ternion) * [11 years ago](https://wordpress.org/support/topic/new-version-31-not-working/#post-6112498) * Also, for the record, I have de-activated and re-activated the plugin as well as deleting and re-installing. * Still does not work. * Plugin Author [websitezcom](https://wordpress.org/support/users/websitezcom/) * (@websitezcom) * [11 years ago](https://wordpress.org/support/topic/new-version-31-not-working/#post-6112589) * Just for the plugin, or your entire administration area? * [robert3harrison](https://wordpress.org/support/users/robert3harrison/) * (@robert3harrison) * [11 years ago](https://wordpress.org/support/topic/new-version-31-not-working/#post-6112620) * As I said, the admin screen for the plugin. * Plugin Author [websitezcom](https://wordpress.org/support/users/websitezcom/) * (@websitezcom) * [11 years ago](https://wordpress.org/support/topic/new-version-31-not-working/#post-6112678) * Can you send me a screenshot? * Also, just to confirm, it would be worthwhile to delete all plugin files, and redownload from WordPress.org. * [pseuss](https://wordpress.org/support/users/pseuss/) * (@pseuss) * [11 years ago](https://wordpress.org/support/topic/new-version-31-not-working/#post-6112684) * Hey, * I have the same problem.

Then install it again so you can get the most recent files. There was an issue for a short period of time where not all of the plugin files were being downloaded. * Also, it needs the permissions fixed to work properly, which is why that notice is present. * Keep in mind that you may have version 3.1, but the current version 3.1 up on WordPress.org is different. * [jasondunn](https://wordpress.org/support/users/jasondunn/) * (@jasondunn) * [10 years, 12 months ago](https://wordpress.org/support/topic/new-version-31-not-working/#post-6112693) * I set the permissions to 777, and the warning message went away. But even after that, under the settings for the app, I get nothing but blank screens for any of the three menu items. I’ve already deleted and re-downloaded the plugin. Any other ideas? * Plugin Author [websitezcom](https://wordpress.org/support/users/websitezcom/) * (@websitezcom) * [10 years, 12 months ago](https://wordpress.org/support/topic/new-version-31-not-working/#post-6112705) * Would it be possible for you to turn on debugging and see what the error is? * In wp-config.php, you can turn on debugging with this: * define(‘WP_DEBUG’, true); * Plugin Author [websitezcom](https://wordpress.org/support/users/websitezcom/) * (@websitezcom) * [10 years, 12 months ago](https://wordpress.org/support/topic/new-version-31-not-working/#post-6112707) * I found the issue. You must be using an older version of PHP. I had a piece of code that used something that was relatively recent for PHP. * Version 3.1.1 should fix this. It will be live momentarily on WordPress.org. * Plugin Author [websitezcom](https://wordpress.org/support/users/websitezcom/) * (@websitezcom) * [10 years, 12 months ago](https://wordpress.org/support/topic/new-version-31-not-working/#post-6112714) * All versions have this fixed and it is confirmed after version 3.1.1. * Resolving the topic.
