Clients Unable to Sign-Up

The form looks great on the backend and the frontend. However, the plug-in simply does not perform well consistently. One address will be accepted, but the second one will not. The third email address may or may not be accepted, then the fourth one will not.

There is a very long forum with similar complaints. The only solutions given were the disable-everything-else-on-your-website-then-create-a-new-event-on-getresponse/mailchimp-and-if-that-does-not-work-then-it’s-them-and-not-us kind of response.

Not working with iContact

This plugin was working great and then it suddenly stopped working.

I have a “cannot fetch signup form” error when trying to add in new optin subscribers. I’ve deactivated, and re-activated the plugin — same issue.
I’ve deleted and re-installed the plugin — still the same issue.

Please advise.

Used to work, then stopped working

When I original installed this plug in, it was working seamlessly with my contact. Then out of the blue it stopped working. I hadn’t received an opt ins for quite some time until someone brought it to my attention. It is a major inconvenience (having to remove this from each page it was operating on) that this company doesn’t figure out a way to resolve this issue when it was working just fine prior.

  • Added shortcode for handling text in different languages. It allows those who run a multilanguage website to have different texts shown. Shortcode is [optinforms_translate lang=”en_US”]Text[/optinforms_translate]. The lang parameter accepts the language code, so if you have a website in English and Spanish you could use this as the form title [optinforms_translate lang=”en_US”]Subscribe[/optinforms_translate][optinforms_translate lang=”es_ES”]Suscribir[/optinforms_translate]
