HTML stripped from form

    Dear all,

    There seem to have been some enhancements in CF7 that seem to strip various types of HMTL from the form field. What has happened – this kills my forms (which are full of HTML). Any suggestion what is happening / how to fix this would be most appreciated.

    Example: I input this in the form field….
    <span style=”display:none”>
    [text campagne default:post_meta]
    [text bron max_length:12 default:get default:post_meta]
    </span>

    Result after saving the form:
    <span>
    [text campagne default:post_meta]
    [text bron max_length:12 default:get default:post_meta]
    </span>

    The style attribute has been deleted – all types of other HTML are also stipped all of a sudden…..

    Where can we see the website in question?

    040energie.nl/040zon
    for a form example

    Could it be that the wordpress editor is used – that also strips much html.

    Config info:
    PHP (7.3.33)
    WordPress 6.0.3
    Theme: customized from TwentyTwelve Version: 3.7 with heavy CSS mods + very minor PHP extensions
    CF7 plugin Version 5.6.4 (NL)
    Contact Form 7 Extension For Mailchimp version 0.5.62
    Honeypot for Contact Form 7 Version 2.1.1
    Contact Form DB Versie 2.10.36 (no longer maintained as far as I know – we’re working on it).

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

    Theme is indicated: twentytwelve is the base – css and very ninor cusomizations through a child theme.

    There is a whole list of active plugins, maybe there is interaction with Classic Editor?

    Bummer – even with classic editor disabled the problem persists.

    Try switching to the default theme, deactivating all plugins excluding Contact Form 7, Akismet Anti-Spam and Classic Editor, and clearing all cache data.

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

    Deactivated the plugins – not all at once but groups at a time – no effect.
    Same with theme – no effect.
    ??

    Where can this filtering of the HTML tags come from – it is not just random error behaviour – there must be some reason why that all of a sudden kicks in?
    Specifically it filters <script> and so disables the javascipt extensions with the forms.

    I remember I had a problem with another plugin related to a specific configuration used in our wordpress setup: we use a subdirectory to do the wordpress install – so not at the root of the webserver. It also caused massive problems when WP introduced the blockeditor since it “upset” the rest-api.

    See the general setup for wordpress from the wordpress menu:

    Are you logged-in as an Administrator?

    (@mcvlot)

    Yes, logged in as admin.

    Tried an older version of the plugin, version 5.5.6, but also that has no effect.

    I am not sure when the problemen appeared. Very recently I think. I sometimes edit some text in the forms which did not given problemen until quite recently. Say max 2 months back all worked well I think. Not 100% sure though.

    Isn’t the 040energie.nl site a Multisite install? If so, try it as a Super Admin user.

    Hello Takayuki,

    No, it is a single install site, just a slightly different directory structure on the server.

    Update: it seems indeed to be a super-user problem. Somehow WordPress thinks our installation is in multi-site mode. It never did so before. There were some other functions that started to refuse input with certain types of HTML content.

    The hypothesis is that it is related to the permission “unfiltered_html”.
    The problem is how to get out of this “trap”: maybe we should “patch” the
    wordpress installation to force it to single site mode or to ro prevent “unfiltered_html” in some other way.

    The thing that makes our site a bit different is that the root for the wordpress install is not in the main directory but in a subdirectory of the main directory – a feature typical for multi-siteconfiguration.

    Any tip on how to “circumvent this issue’ is appreciated. Probably the problem is in the wordpress core.

    Note: loaded a plugin “unfiltered MU”: this fixed it. It is a silly patch – but the short route to getting on with it….
