# Help, tpm not working! Here's the list of issues users had with `tpm`: > Nothing works. `tpm` key bindings `prefix + I`, `prefix + U` not even defined. [Issue #22](https://github.com/tmux-plugins/tpm/issues/22) - Do you have required `tmux` version to run `tpm`?
Check `tmux` version with `$ tmux -V` command and make sure it's higher or equal to the required version for `tpm` as stated in the readme. - ZSH tmux plugin might be causing issues.
If you have it installed, try disabling it and see if `tpm` works then. > Weird sequence of characters show up when installing or updating plugins [Issue #25](https://github.com/tmux-plugins/tpm/issues/25) - This could be caused by [tmuxline.vim](https://github.com/edkolev/tmuxline.vim) plugin. Uninstall it and see if things work. > "failed to connect to server" error when sourcing .tmux.conf [Issue #48](https://github.com/tmux-plugins/tpm/issues/48) - Make sure `tmux source ~/.tmux.conf` command is ran from inside `tmux`.
