Although that’s a pretty old version, I do claim to support the same as WordPress, which is 5.2.4 and up. * However, you may still have problems because this error occurred while handling another error.

Issus is still the same …. loco cannot safe or sync.

setCallee note. Please dont mind if there is no change of the problem itself. I wait to get answer by the enigma pro team for a theme error.

You don’t appear to have updated to the development version. [The fix](https://github.com/loco/wp-loco/blob/059279aa1370aeed9e343c81a79fa2efd7b7db36/src/error/AdminNotices.php#L47) clearly shows one argument being passed to debug_backtrace with setCallee being called from [line 51](https://github.com/loco/wp-loco/blob/059279aa1370aeed9e343c81a79fa2efd7b7db36/src/error/AdminNotices.php#L51), not 48. * 2. Your log shows database connection errors. This is perhaps your root cause. * Thread Starter [wp0newbie](https://wordpress.org/support/users/wp0newbie/) * (@wp0newbie) * [7 years, 5 months ago](https://wordpress.org/support/topic/error-code-500-while-saving-any-translation/#post-10998090) * First i have to thank you to be patient with me 🙂 * I Updated wrong … was my failure.
