I may well have to look for a more reliable alternative in the near future. * [jemmasta](https://wordpress.org/support/users/jemmasta/) * (@jemmasta) * [9 years ago](https://wordpress.org/support/topic/4-8-version-doesnt-work/#post-9198389) * I have the exact same issue. Any easy way to rollback for now, couldn’t find zip for the previous version. * [justdave](https://wordpress.org/support/users/justdave/) * (@justdave) * [9 years ago](https://wordpress.org/support/topic/4-8-version-doesnt-work/#post-9198610) * [https://downloads.wordpress.org/plugin/contact-form-7.4.7.zip](https://downloads.wordpress.org/plugin/contact-form-7.4.7.zip) * Thread Starter [Max](https://wordpress.org/support/users/makspostal/) * (@makspostal) * [9 years ago](https://wordpress.org/support/topic/4-8-version-doesnt-work/#post-9198847) * Hi, Thanks! * I haven’t any CF7 extentions. May I just replayce files on my server from CF7.4.7. zip without any changes in DB? * Thread Starter [Max](https://wordpress.org/support/users/makspostal/) * (@makspostal) * [9 years ago](https://wordpress.org/support/topic/4-8-version-doesnt-work/#post-9198865) * After I had replaced files form submit have started to work properly. * I’m not a proggrammer, but I think the cause of this issue in: _Added custom REST API endpoints for Ajax form submissions._ Maybe 🙂 * [Hydro1313](https://wordpress.org/support/users/hydro1313/) * (@hydro1313) * [9 years ago](https://wordpress.org/support/topic/4-8-version-doesnt-work/#post-9198914) * Yes this also happened to me and the resolution was to rollback to CF7 4.7. Everything works perfectly fine with 4.7. * [burlingtonpress](https://wordpress.org/support/users/burlingtonpress/) * (@burlingtonpress) * [9 years ago](https://wordpress.org/support/topic/4-8-version-doesnt-work/#post-9199613) * Also having an issue with 4.8. All I get is the spinning arrows after pressing submit. Rolled back to 4.7 and all works fine again. * [sylen](https://wordpress.org/support/users/sylen/) * (@sylen) * [9 years ago](https://wordpress.org/support/topic/4-8-version-doesnt-work/#post-9204797) * Hi Problem with REST API if use plugin Shield Security by IControl (or similar plugin security) in Shield dashboard config – off “lockdown” (Disable) The Anonymous Rest API System.

If permalinks need to be rebuilt to fix a problem, then wordpress.org should rebuild them on plugin update etc. * Thread Starter [Max](https://wordpress.org/support/users/makspostal/) * (@makspostal) * [8 years, 12 months ago](https://wordpress.org/support/topic/4-8-version-doesnt-work/#post-9224457) * Thanks, but this only works for one of my sites. * [burlingtonpress](https://wordpress.org/support/users/burlingtonpress/) * (@burlingtonpress) * [8 years, 12 months ago](https://wordpress.org/support/topic/4-8-version-doesnt-work/#post-9224492) * I don’t have time to test this thoroughly, but I’ve noticed 4.8 working on sites that have mod_security disabled. * [drazon](https://wordpress.org/support/users/drazon/) * (@drazon) * [8 years, 12 months ago](https://wordpress.org/support/topic/4-8-version-doesnt-work/#post-9226923) * I’m experiencing the same issue on several of my sites as well. Rolling back to 4.7, However I have one website on the same server (with enabled modsecurity) and same configuration that doesn’t show this error. - This reply was modified 8 years, 12 months ago by [drazon](https://wordpress.org/support/users/drazon/).
