Even though I’ve tested it multiple times on my end I still can’t replicate it hence why I’d need access to the site to see what’s happening on your end. * Thread Starter [leogc](https://wordpress.org/support/users/leogc/) * (@leogc) * [6 years, 12 months ago](https://wordpress.org/support/topic/e_error-after-version-1-0/#post-11659550) * As said we are unable to give away any log in in the moment, besides that, FTP is something we would never give away, sorry. And in Admin i have given you all what is showing to me, so we will see if the error will be still there after the next update. * You can tell me what you like to see and i create screenshots if that helps. * Plugin Author [Alessandro Tesoro](https://wordpress.org/support/users/alessandrotesoro/) * (@alessandrotesoro) * [6 years, 12 months ago](https://wordpress.org/support/topic/e_error-after-version-1-0/#post-11659594) * Hi [@leogc](https://wordpress.org/support/users/leogc/) * I really appreciate your help, unfortunately I’m shooting in the dark here, could you please download this slighly modified version of the plugin [https://www.dropbox.com/s/dmurw7lqly7g6lp/posterno.zip?dl=0](https://www.dropbox.com/s/dmurw7lqly7g6lp/posterno.zip?dl=0), unzip it and replace the existing folder into your site to see if that helps? * Unfortunately ftp would have been the only way because I’d need direct access to the file of the new import/export functionality to see how the composer autoloader is loading but no worries I understand if you don’t want to mail me the ftp details, that’s absolutely fine. * Plugin Author [Alessandro Tesoro](https://wordpress.org/support/users/alessandrotesoro/) * (@alessandrotesoro) * [6 years, 12 months ago](https://wordpress.org/support/topic/e_error-after-version-1-0/#post-11659820) * Hey [@leogc](https://wordpress.org/support/users/leogc/) * I’ve identified the issue, it’s an incongruency with folder names and how web servers read folder names. My local server uses a non case-sensitive system while web server use case-sensitive systems. * Once again apologies about the issue, I’m releasing a fix shortly in v1.0.1 * Thread Starter [leogc](https://wordpress.org/support/users/leogc/) * (@leogc) * [6 years, 11 months ago](https://wordpress.org/support/topic/e_error-after-version-1-0/#post-11662294) * Ah ok, so i don’t need to try it with the dropbox file, so i wait till the release 🙂 * Thread Starter [leogc](https://wordpress.org/support/users/leogc/) * (@leogc) * [6 years, 11 months ago](https://wordpress.org/support/topic/e_error-after-version-1-0/#post-11662352) * Ok it works again!
