Sessions

All I know is thatt when I log in I get an entry

ci_session83caf69c2f12713c5348f461503447b7

Containing

__ci_last_regenerate|i:1546369534;logged_in|a:5:{s:7:"user_id";s:2:"21";s:9:"user_name";s:6:"Pamela";s:10:"user_email";s:29:"[email protected]";s:20:"type_of_last_payment";s:0:"";s:9:"user_type";s:6:"seller";}successmsg|s:31:"You are successfully logged in.";__ci_vars|a:1:{s:10:"successmsg";s:3:"new";}



in ci_session



Then ci_session9a14cc56047430275f53a9d9be52dd6d

which is completely empty


then

ci_sessionc7877c62d115003cf62ec4eb05e753de

containing

__ci_last_regenerate|i:1546369534;




Then more completely empty ones





Why? The code hasn't been changed since it was last working. When I look as the session stored on my PC the value is one of the totally empty ones. What is going on? I have no idea how it is supposed to work but surely those extra entries shouldn't be there?







I have done some more testing


Every time I go to anew page I get something like


ci_sessionc7877c62d115003cf62ec4eb05e753de

containing

__ci_last_regenerate|i:1546369534;



in ci_session and the session value is written to my PC





When I try and log in the Session value on my PC isn't being changed






Hmm it is codeignitor 3.0.6

And the Host has upgraded to PHP 7.2.6 since it was working



Could that be the problem?


How do I upgrade to the latest codeognitor? I didn't write the site originally and I hadn't realised it was that old
