This is a client’s website that I’ve just inherited to do regular maintainence on. I dread the thought of trying to deactivate each plugin in turn as it will have to be on the ‘live’ site. There is no room on his server for a live site and a download of his 80GB site will take at least two days! If I revert to the previous version of CF7 plugin and it works, is it safe to keep it?
Thanks, James

Sorry, I should have said there is no room on his server for a staging/dev site, so I’d have to download the live site to a localhost and try disabling stuff from there, but it would take three days and in the meantime he can’t run his wedding photography business!

Which one is the theme?

A good question, Takayuki. The theme was a ‘custom’ theme, and I haven’t a clue what it was based on, only that every page uses a custom php template. It is not updateable as the whole theme was made from scratch, though I suspect the web developer (who cannot be traced) copied it from somewhere. I guess it is likely that some jQuery/JS is deprecated as the site was built in 2015. I think the best thing to do for the time being, just to get is site working, is to roll back to the previous cf7 version. Where can I download it please? Cheers, James.

Just an update. I found cf7 5.6.2 and it still gives the same problem on the tick box.
I will try 5.6.1 and then I think I will have to start deactivating other plugins, unless you can find another solution.
Cheers
James

5.6.1 also produces the same problem, so I guess it is another updated plugin causing the problem? James.

Takayuki, I’ve also tried deactivating a few of the plugins associated with cf7, namely Conditional Fields for Contact Form 7
Contact Form 7 digital signature add-ons
Contact Form CFDB7
but none of these make any difference.

Just to be certain, this is the right code for the tick-box?

<div class="checkbox_wid_info">
[checkbox* terms class:checkbox_text id:terms_condition exclusive ""] I agree to the <a href="https://www.simplyphotographic.co.uk/terms-and-conditions">Terms & Conditions.</a>
</div>

<div class="input_wrap">
<div class="input_label">
<p>Please follow the re direct to our T&C e-signature contract ready for signing. <br>
Please press the Submit button.</p>
</div>
<span class="star">*</span>
</div>

<div class="submit">
[submit class:submit_button id:submit_button "Submit"] <div class="social"><span>Please like us:</span><a href="https://www.facebook.com/simplyphotographic1" target="_blank" class="social_icon fb"></a><a href="https://www.instagram.com/simply_photographic_/" target="_blank" class="social_icon ins"></a>
</div>

Finally, Takayuki, I have contacted wp-e-signature, because the ‘Submit’ button redirects to their e-signature document, and I think this might be where the problem lies. I don’t think cf7 is showing the ‘fields need to be completed’ error because of the form, as the fields are all completed. So I think it’s not able to find the redirect page (even though I’ve recreated it several times). Hope this helps in trying to sort out this problem. Many thanks, James.

So, it isn’t a problem with e-signature, it comes back to a problem with cf7 and the fact that the submit button doesn’t work correctly. Where do we go from here?
