Hello to everyone and Happy New Year!
I just installed Invoice Plane. Everything seems to be working just fine apart from one thing. If I change the display language (System Settings -> General) to Greek (my native tongue ) whenever I press Save, or OK it logs me out (the system invalidates Session). It does keep any change I made but it logs me out!
I tested also with English, German and Italian but this problem does not occur. It works fine there. After a little digging I found in the log that every time the system logs me out this is added.
ERROR - 2017-01-04 20:43:16 --> Severity: Notice --> unserialize(): Error at offset 197 of 239 bytes /opt/lampp/htdocs/invoice/system/libraries/Session.php 741 ERROR - 2017-01-04 20:43:16 --> Severity: Notice --> unserialize(): Error at offset 197 of 239 bytes /opt/lampp/htdocs/invoice/system/libraries/Session.php 741
197 and 239 (offset x of y bytes) are the usual numbers but from time to time it is different (I assumed it has to do with what I was trying to save/modify).
Since this only occurs in Greek I believe it has something to do with the translation files. I looked but nothing seems to be out of the ordinary.
