Can you try disabling that plugin and see if that resolves it? * Thread Starter [Roharniac](https://wordpress.org/support/users/rowan-ryco/) * (@rowan-ryco) * [8 years, 6 months ago](https://wordpress.org/support/topic/migration-issue-8/#post-9762022) * Disabling plugin makes the PROD site work. DEV site works ok with the plugin installed which is strange. DEV and PROD exactly same website * I thought it could be a difference with value of variable $tmpdir or what basedir is set to? and where ever that is set to I need to add permissions on that folder? * Here is a image of my other plugins [https://imgur.com/a/tVAXx](https://imgur.com/a/tVAXx) is there any plugins that it could be conflicting with? * Also this is a multisite, does this plugin work properly with multisite – it seems like it does because it works on my DEV site - This reply was modified 8 years, 6 months ago by [Roharniac](https://wordpress.org/support/users/rowan-ryco/). - This reply was modified 8 years, 6 months ago by [Roharniac](https://wordpress.org/support/users/rowan-ryco/). - This reply was modified 8 years, 6 months ago by [Roharniac](https://wordpress.org/support/users/rowan-ryco/). * Plugin Author [launchinteractive](https://wordpress.org/support/users/launchinteractive/) * (@launchinteractive) * [8 years, 6 months ago](https://wordpress.org/support/topic/migration-issue-8/#post-9762181) * I don’t think any of the other plugins would be conflicting, but you do have a lot of them. Are they all necessary? Having that many could impact on your site performance. * MMR should work as a multisite. I don’t do a lot of multisite setups but I did do some basic testing with it. * Thread Starter [Roharniac](https://wordpress.org/support/users/rowan-ryco/) * (@rowan-ryco) * [8 years, 6 months ago](https://wordpress.org/support/topic/migration-issue-8/#post-9762226) * Yes i need these plugins as there doing specific things.

You can try to remove the plugins from your plugin directory. That should allow you to get to the admin.
