Title: Errors after upgrade Last modified: August 21, 2016 --- # Errors after upgrade * Resolved [StevenP94](https://wordpress.org/support/users/stevenp94/) * (@stevenp94) * [12 years, 6 months ago](https://wordpress.org/support/topic/errors-after-upgrade-2/) * I just installed the latest upgrade, and start to receive alerts from my log inspector: * PHP Fatal error: Call to undefined function wptouch_post_classes() in /var/www/ fabibcc/wp-content/plugins/wptouch/themes/foundation/default/formerror.php on line 4 * How to fix ? * [http://wordpress.org/plugins/wptouch/](http://wordpress.org/plugins/wptouch/) Viewing 15 replies - 1 through 15 (of 15 total) * [Matt Robinson](https://wordpress.org/support/users/mattyrob/) * (@mattyrob) * [12 years, 6 months ago](https://wordpress.org/support/topic/errors-after-upgrade-2/#post-4393175) * [@stevenp94](https://wordpress.org/support/users/stevenp94/), * That would seem to me like an incomplete update. Remove the plugin and re-install it and see if that helps. * [GRM](https://wordpress.org/support/users/grm/) * (@grm) * [12 years, 6 months ago](https://wordpress.org/support/topic/errors-after-upgrade-2/#post-4393176) * [@stephen94](https://wordpress.org/support/users/stephen94/) I have repeatedly been getting the same message in the error log since updating to v3.1.1. Please report back if a re-install works for you. * [BraveNewCode Inc.](https://wordpress.org/support/users/bravenewcode/) * (@bravenewcode) * [12 years, 6 months ago](https://wordpress.org/support/topic/errors-after-upgrade-2/#post-4393182) * We fixed some code that might be responsible for that error on some installations. We’re diagnosing issues reported here in the forums and will push out a fix release soon once we can include a batch of improvements. * Thread Starter [StevenP94](https://wordpress.org/support/users/stevenp94/) * (@stevenp94) * [12 years, 6 months ago](https://wordpress.org/support/topic/errors-after-upgrade-2/#post-4393209) * [@grm](https://wordpress.org/support/users/grm/) Sorry to tell you that reinstalling 3.1.1 from scratch doesn’t solve the problem. We all must wait for the next update, I hope will be soon 😀 * [BraveNewCode Inc.](https://wordpress.org/support/users/bravenewcode/) * (@bravenewcode) * [12 years, 6 months ago](https://wordpress.org/support/topic/errors-after-upgrade-2/#post-4393210) * Yes, re-installing won’t fix the issue, only an update. We’re working on a batch of fixes, a new release will be out thursday. * [hapatite](https://wordpress.org/support/users/discojing/) * (@discojing) * [12 years, 6 months ago](https://wordpress.org/support/topic/errors-after-upgrade-2/#post-4393211) * Re-install fixed it for me, thanks! * Thread Starter [StevenP94](https://wordpress.org/support/users/stevenp94/) * (@stevenp94) * [12 years, 6 months ago](https://wordpress.org/support/topic/errors-after-upgrade-2/#post-4393244) * I hope for a quick solution: I’m getting tons af alert emails from my server 😛 * [kchayka](https://wordpress.org/support/users/kchayka/) * (@kchayka) * [12 years, 6 months ago](https://wordpress.org/support/topic/errors-after-upgrade-2/#post-4393251) * Win7 WAMP localhost and WP 3.8, upgraded WPT from 1.9.8.9 to 3.1.1, now admin screens are all blank. * e.g. on the What’s New page I see a [Notifications] button (that does nothing when clicked), the page heading, followed by a line that only says “Loading image”. The rest of the page is blank. * I deactivated the plugin and reinstalled but no difference. Will the next upgrade address this issue, too? * [BraveNewCode Inc.](https://wordpress.org/support/users/bravenewcode/) * (@bravenewcode) * [12 years, 6 months ago](https://wordpress.org/support/topic/errors-after-upgrade-2/#post-4393263) * Please upgrade to version 3.1.3 and see if it fixes your issue. * [kchayka](https://wordpress.org/support/users/kchayka/) * (@kchayka) * [12 years, 6 months ago](https://wordpress.org/support/topic/errors-after-upgrade-2/#post-4393266) * No, WPT 3.1.3 did not fix anything for me. * [BraveNewCode Inc.](https://wordpress.org/support/users/bravenewcode/) * (@bravenewcode) * [12 years, 6 months ago](https://wordpress.org/support/topic/errors-after-upgrade-2/#post-4393267) * You’ll also want to ensure that your server is setup to allow WPtouch to write its themes and extensions. That means setting the /wp-content/wptouch-data/ directory and contents to 777. If there is no wptouch-data directory, it is likely because the wp-content directory is not allowing it to be created. * Once permissions are verified as given, WPtouch v3.1+ should complete its installation allowing all admin areas to be displayed. * Details are in this documentation: [http://www.bravenewcode.com/support/knowledgebase/themes-or-extensions-cannot-be-downloaded/](http://www.bravenewcode.com/support/knowledgebase/themes-or-extensions-cannot-be-downloaded/) * [kchayka](https://wordpress.org/support/users/kchayka/) * (@kchayka) * [12 years, 6 months ago](https://wordpress.org/support/topic/errors-after-upgrade-2/#post-4393268) * It’s not a permissions problem. The wptouch-data directory was created without any problem. I even removed the 1.9x version and reinstalled the 3.1.3 plugin. The directory was recreated as it should but the admin screens are still blank. If I use Firebug to change all the display:none rules to display:block I can get to the admin settings but this is a bad way to go about it, and I certainly couldn’t ask a client to do that. * [BraveNewCode Inc.](https://wordpress.org/support/users/bravenewcode/) * (@bravenewcode) * [12 years, 6 months ago](https://wordpress.org/support/topic/errors-after-upgrade-2/#post-4393269) * Please update to 3.1.4 and let us know if it solves your issue. * [kchayka](https://wordpress.org/support/users/kchayka/) * (@kchayka) * [12 years, 6 months ago](https://wordpress.org/support/topic/errors-after-upgrade-2/#post-4393272) * admin screens are displaying now. thanks * [BraveNewCode Inc.](https://wordpress.org/support/users/bravenewcode/) * (@bravenewcode) * [12 years, 6 months ago](https://wordpress.org/support/topic/errors-after-upgrade-2/#post-4393281) * Glad we were able to help! * If you don’t mind, we would welcome your posting a review of the plugin: [http://wordpress.org/support/view/plugin-reviews/wptouch#postform!](http://wordpress.org/support/view/plugin-reviews/wptouch#postform!)
