CA certificate error

[mourad13]

Hello,

I have a problem on my site while generating PDF.
I have a CA certificate which expired yesterday.
The site still works, but I have errors, for example, when generating pdf:
Error messages: \ nerror: 1416F086: SSL routines: tls_process_server_certificate: certificate verify failed in /var/www/a3s/modules/fpdf/fpdf.php on line 1250PHP message: PHP Warning: getimagesize (): Failed

should it be deleted?

Like : if your finger hurt, you can do two things : cut (delete) it off, or heal it.
I advise you to consider the second choice.

Deal with this :

You actually answered your own question.

@gertjan Having never had this problem, I preferred my insured before doing it.
But thank you for your humor.
However, this link would have been more interesting.
