Hello,
Strange thing happened. Recently updated wordpress to the latest ver, purchased theme from tielabs.com and contact form was working smoothly, without any problems. Then, afetr configuring separate sidebars for home page and other pages, contact form stopped working even after setting everything as it was before changes. It just writes that mail could not be sent with red border. Any advice would be very appreciated. Thank you!
P.S. Changed language of wordpress recently as well.
