Working with PDO gives error.

[yahyaerturan]

Hi, I am using PDO driver in Codeigniter 3.x. When I enabled DevelBar, it throws an error:

error: {type: "PDOException", message: "You cannot serialize or unserialize PDO instances",…}
    file: "/system/libraries/Cache/drivers/Cache_file.php"
    line: 104
    message: "You cannot serialize or unserialize PDO instances"
    type: "PDOException"

How can I fix it? Thanks for any help.

Hello @yahyaerturan
I think this error is related to your PHP version and some overriding on PDO driver. can you give me more details !

[yahyaerturan]

Sure. I am working with PHP 7.1 - When I set my Codeigniter to use Mysqli, CI and Develbar works like a charm. When I switch to use pdo, CI works but Develbar gives upon error. I don't know what more details I can provide.

Hello @JCSama. Now it is working with PDO as well, thanks! Sorry for late response. As I made some minor changes on my copy, I had to apply all the changes line by line to test if it is working 👍
