Hello, we have already installed the version 1.4 and using it without big problems. I tried to upgrade from 1.4 to 2.0 without any luck. My process was the following: 1. I stop the mattermost service 2. I backup the database and the configs 3. I decompress the new tar 4. Copy the backed up config files back to the Config folder 5. Start the service 6. Restart nginx Then if i try to access the webpage i get an almost blank page without login form. The logs folder is empty. The only clue i have that all the browsers (Chrome and Firefox) logs an error to the developer console. It says: “Uncaught TypeError: window.setup\_signup\_team\_page is not a function”. And there are some other errors where the application tries to download non exsisted js libraries from our server [https://mattermost.mycompany.com/static/js/libs-5189.min.js](https://mattermost.mycompany.com/static/js/libs-5189.min.js) and [https://mattermost.mycompany.com/static/js/libs-5189.min.js](https://mattermost.mycompany.com/static/js/libs-5189.min.js). These libraries are there but with a different version number: 5950. If i revert back to the old 1.4 version (with the same process i mentioned above) everything works fine. So now we stucked. What can be the problem? Do you have any idea what should i try? What other information should i provide to investigate this problem? (I am planning to do a clean install in a different location if i will have time to do that). Any help appriciated. Thanks ---

Hi Kemy, appreciate the report, not sure what it is, is anyone else from the community hitting this? ---

Adding a GitHub issues thread where others are hitting a similar issue with v1.4: [https://github.com/mattermost/platform/issues/1899](https://github.com/mattermost/platform/issues/1899) Anyone from community hit this error message and figured out the solution? When we tested the configuration internally it worked. @Kemy, can you share which OS you’re using? ---

Thank you for your response. We use Ubuntu 15.04. I didn’t have time to try a clean install but i should do it in the near future because the team can’t wait for the upgrade. 🙂
