# JS / 404 errors

 * Hey [@webfactory](https://wordpress.org/support/users/webfactory/),
 * we are an agency using your plugin on several dozens of WP installations.
 * Everywhere we find a console error we haven’t seen in the past:
 * `GET https://[DOMAIN.TLD]/wp-content/plugins/contact-form-7/includes/js/scripts.
   js?ver=5.6.2 [HTTP/2 404 Not Found 680ms]`
 * On one of the installations we even get additional jQuery errors (“Uncaught ReferenceError:
   jQuery is not defined”, “Uncaught TypeError: e.indexOf is not a function”) and
   the whole maintenance page doesn’t load anymore when we reload it via F5 or CTRL
   +F5.
 * In another thread ([https://wordpress.org/support/topic/maintenance-page-spinning/](https://wordpress.org/support/topic/maintenance-page-spinning/))
   we read that you already found this problem but we aren’t completely sure if 
   it is the same.
 * We would prefer not to switch all the installations to your or another maintenance
   solution if your update fixing this problem is already coming up.
 * So could you please tell us when you plan to release the update/fix?
 * Thank you very much for your great work,
    -doffine

 * Hi,
    As the URL clearly shows, that JS is a part of the Contact Form 7 plugin.
   Our devs will see if they can block that but I can’t promise anything because
   it’s clearly not coming from our plugin.

 * Hi [@webfactory](https://wordpress.org/support/users/webfactory/),
 * you are right, as soon as we deactivate Contact Form 7 the error is gone instantly.
 * Now we have a problem: Contact Form 7 has 5M+ installations and we, amongst 5
   million others, use it on many sites. So it can’t be a permament incompatibility.
 * Else one would have to decide to either use your plugin or Contact Form 7. This
   cannot be in your interest.
 * So it’s great that your devs look into it and try to fix this incompatibility.
   Perhaps you could contact CF7 devs, too, to find a solution together?
 * But for us as end users now it is only important to know: How long will we have
   to wait until you say “It’s fixed.” or “We won’t/cannot fix it. Get rid of Contact
   Form 7 or find yourself another maintenance plugin because of this ongoing incompatibility.”
 * We have many sites where the maintenance page loads only with errors or simply
   gets stuck with a black screen or the ever spinning wheel at this moment. Chrome
   seems to be a bit more robust here than Firefox by the way.
 * Disabling CF7 in all of these whenever maintenance is on is additional work, 
   impractical and cannot be a solution forever.
 * So please let us know what timeframe you intend to use for trying to find a solution:
   More like 3 days, a week, a month or half a year? So when should we start looking
   for alternatives. It would be a pity if we just had replaced all Maintenance 
   plugins and their sites and one day later the solution is there.
 * Greetings and, of course, many thanks for your work,

 * Hello [@webfactory](https://wordpress.org/support/users/webfactory/),
 * just want to let you know: We updated all of our installations to v4.02, and 
   the errors are gone now everywhere.
 * Thanks for your good and quick work,

   you 🙏 [https://wordpress.org/support/plugin/maintenance/reviews/#new-post](https://wordpress.org/support/plugin/maintenance/reviews/#new-post)
