My web host disabled proc_open function in php and I can\'t send emails anymore.
I get this error log:
> proc_open() has been disab
Check and changes are your php.ini has this line.
disable_functions = exec,system,dl,passthru,chown,shell_exec,popen,proc_open
Check this a list of functions disabled by safe mode here.
UPDATE
Once you found that, follow below instruction:
Remove the proc_open from the disable_functions at php.ini file
OR
Ask your hosting provider to remove the string above if you don't have an access/right to do that.
