Trouble with HTTPS certificate

[Andre Garzia]

Hi folks,

can someone shed a clue on this error message trying to post to a HTTPS 
secure url?

error -Error with certificate at depth: 1  issuer   = /C=ZA/ST=Western 
Cape/L=Cape Town/O=Thawte Consulting cc/OU=Certification Services 
Division/CN=Thawte Server CA/Email=server-certs at thawte.com  subject  = 
/C=ZA/O=Thawte Consulting (Pty) Ltd./CN=Thawte SSL Domain CA  err 
20:unable to get local issuer certificate

What the hell is happening? my certificate is old?

folks, I need this asap, I need to post to secure urls, any clue would 
be fine.

I am on MacOS X 10.3.9 using Rev 2.5.1 Enterprize.

thanks in advance for the help
cheers
andre
