contact form 7 not submitting

What other plugins and theme do you use on the site?

Hi Takayuki,
I use the following plugins:
– Akismet Anti-Spam
– All in One SEO
– Contact Form 7
– Email Protect
– Flamingo
– Google Analytics for WordPress by MonsterInsights
– WordPress.com Stats

Theme: sodelicious

Try switching to the default theme and deactivating all plugins excluding Contact Form 7, Akismet Anti-Spam, and Flamingo.

Why you are advised to deactivate plugins and switch to the default theme.

Thanks. It works with the default theme so I have an issue with my theme. I’d like to keep using my theme, any suggestions to fix?
