Warning: Wrong Validation Code when Saving Front End

[tflores21]

Hi,

Just upgraded to 3.7 and get the "Wrong Validation Code" warning error when saving edits from the front end. It does not save the changes.

I can edit on the back end with no errors.

Anyone have this issue? I've received no response.

Don't know if you've solved this for yourself or not (as it's been a few days), but I've just had to resolve this for someone.

The repro is on a site upgraded to Joomla 3.7.0, log into the front-end, locate a com_content article and open it for editing. Click Save and you'll likely get

Warning
Invalid validation code

And any changes won't have been saved.


After a bit of digging, In this case, at least, the warning was being raised by the SecurImage plugin.

Prior to the 3.7.0 upgrade, no captcha had been enabled for the front-end editor, and going to Configuration -> Articles -> Editing layout still shows "Allow Captcha on Submit" as "None Selected".


But, disabling the SecurImage plugin led to a white screen on submission of the front-end form (with nothing logged other than a couple of strict standards warnings when error reporting is enabled).

Resolved by going Configuration -> Articles -> Editing Layout, selecting one of the plugins, saving and then setting the form back to "None Selected"

I've not dug in too much, but I'd guess that during upgrade an ID changed or something, so the previous value was now inadvertently pointing at the plugin.

The captcha wasn't visible on the front-end edit page, though the site I've been looking at has some template overrides in place, so it's more than possible it would have displayed on a vanilla template.

It was made a little harder to find by the fact that the securImage plugin doesn't keep it's language strings in either /language or /administrator/language, instead they're within a language directory with the plugin.
