The plot thickens.
I'm having this delay problem with several contact form plugins in a wordpress installation in a subdomain (subdomain2.mydomain.com) where I'm building a site that's not ready to display to the world.
On a lark I installed contact form plugins in a website I maintain at mydomain.com and also in the test version of that website, located at subdomain1.mydomain.com, where I try tweaks before editing the live site. Everything works beautifully in both places, with no delay.
I tried changing the following variables in the problematic installation:
- turned off all plug-ins except the contact form
- changed the theme to the same as the installations that work fine
- changed all email info in the plugin settings (contact, return-path, etc) to be identical to the installations that work fine
- even changed the Wordpress admin email to be the same as on the other installations
...and the problem remains, on that one installation only. Does that clarify where to go next? More likely to be the apache glitch you referred to? I'll open a ticket, but am game to try other suggestions. Thanks.
