Thank you for contacting WPML Support. Before a more detailed look, please, try this basic troubleshooting:
1 - Make sure your server environment meets our minimum requirements as described at: https://wpml.org/home/minimum-requirements/, you can see your current values at your WordPress Dashboard > WPML > Support > Info menu.
2 - Disable all the plugins except the WPML related ones from your WordPress Dashboard > Plugins and see if the issue is gone, if so, activate one plugin at a time untill the culprit one is found.
3 - If the issue persists, temporary change to a default WordPress theme such as the 'TwentySeventeen' theme from your WordPress Dashboard > Appearance > Themes menu.
