I logged in to your site and I was able to visit the back end page that you experienced errors with according to your last update, and it worked as expected (see screenshot).
Were the problems resolved by upgrading WordPress?
If you had an old version of WPML to test on your old version of WordPress and something went wrong, if you are still experiencing problems and you have only just started the work of translating your site, it might not be a bad idea to start from scratch.
You could go to WPML > Support and follow the Troubleshooting link, and at the bottom of that page use the Reset WPML option to delete all existing WPML tables and deactivate the plugin.
Then when you re-activate WPML it would recreate the tables and you would be starting with a clean slate.
(Only do this if you have not already translated much content, and if you are still experiencing unexplained errors.)
