Hello. Yes I had the same problem in all my websites! The problem has been fixed with version 1.5.7.
To fix it, follow these steps:
– connect to your website via FTP or use the file manager of your hosting provider
– navigate to wp-content/plugins directory
– rename language-switcher-for-transposh directory to _language-switcher-for-transposh; this make WordPress deactivate plugin and you’ll be able to access your website again.
– access your admin dashboard and go to the Plugins page
– go back to your FTP software and restore the original name of the plugin (language-switcher-for-transposh)
– from the plugins page of the admin dashboard update the plugin to the version 1.5.7 **while it is deactivated**
?– now you can reactivate the plugin and everything will work fine again.
I’m really sorry and I hope these steps help you to solve the problem. Feel free to contact me at [email protected] if you need some more help.
