Error during DB export

Hi there!

When I try to export WP database with its native tool (Tools > Export) I don’t get the usual XML, but instead I get a cmlsettings file with the following code:

<br />
<b>Warning</b>:  readfile(/homepages/32/d369391738/htdocs/wp-content/uploads/ceceppaml/backup/.tmp1): failed to open stream: No such file or directory in <b>/homepages/32/d369391738/htdocs/wp-content/plugins/ceceppa-multilingua/admin/admin-backup-fn.php</b> on line <b>217</b><br />

Any hint on what can be going wrong?

Thanks in advance! 🙂
