This problem may go away shortly, but I thought it might be worth mentioning. In some cases I have been moving away from Fast Secure Contact form because it is no longer supported, and has been removed from the WordPress plugin list. It is however still one of the best form managers around. I have been searching for something equivalent.
I found Contact Form 7 which is also very popular, and started to use it. I have found some enhancements so that it can do most of what Fast Secure Contact form did, but it is not a 1:1 replacement.
I found out that while it worked perfectly on IE, Edge, Firefox and Chrome, not all aspects of the form was working for Apple devices if there was an attachment for the form, or the recaptcha function (reduces spam) was present it behaved inconsistently. I made an enquiry with the plugin author and found out there is a problem with WebKit which is used in Apple’s iOS. I expect it will be fixed very shortly, in fact I noticed my iPhone has an update pending right now.
One of the symptoms was that if there was the ability add an attachment you could not send the form if you were using an iPhone or Safari (web browser on Mac devices). In another case I found that after posting a message into the form (where the form subsequently presented some new information in the form area), the screen jumped to the top of page. If the form was not visible within the screen area then you would not see the message.
Do check your forms
I recommend testing your forms at least once a month to make sure they are working. There is no reason why they should stop working, but there have been cases where that has happened due to some other problem in the website. Also check them on a mobile device to make sure that works as well. It is good insurance.
If you find a problem, please let me know immediately. If your site is using an SMTP plugin, then there will be a mailbox associated with anything sent from the website. You can check that to see if there are any bounce back messages in there. These often indicate whether there is a problem or not.
On many sites there are one of two contact forms used, one is called Form Manager (generally very old sites) and the other is called FS Contact Form. Neither of these form handlers are available now through the WordPress repository. Neither of them are supported any more by their authors. It is very much in your interests to replace them.
I am recommending the removal of the existing contact forms on all websites and replacement with Contact Form 7 and another plugin called Contact Form Redirection.
Both of these are supported contact forms and have current versions compatible with WordPress version 4.9.5.
By using these two plugins it will be possible to achieve the following:
- Contact Form similar in appearance to your current form
- Ability to upload an attachment
- Supports Google Recaptcha version 2.00 (to reduce spam).
- On screen message to sender to confirm message has been sent
- Redirection to a Thank You page
- Ability to format the message that is returned to your organisation
- Send a copy of the submitted message to the author to confirm submission
It can probably do many more things, but these are a superset of what we are currently supporting on the most advanced sites.
The downside is Contact Form 7 is not that intuitive to use if you are a novice user compared to the former versions. However it is one of the most popular plugins for managing user forms.
