I Get the Same Errors...
I been dealing with this for months now and cant get it fixed... My GD lib doesnt work..... And i have made every upgrade in that list you posted... i started at version 1.4.14 ...and made all version upgrades inbetween up to 1.5.0... But now all i can do is disable the security features that use GD .... is there a way to fix this so i can enable the use of the GD lib.???
I was hoping that upgrading to 1.5.0 would fix the problem but it doesnt. i spent countless wasted hours trying to find a fix.
