Create an incoming call animation for a Joomla site

The incoming call icon highlights your phone number. Make it easy for visiting customers to contact you. This is a useful tool for e-commerce sites.
You can install the JMP Incoming Call module and use it on Joomla 3, 4 and 5.
Parameters you can customize:

- Phone number
- Color
- Icon position
This is the fastest and easiest way. If you don't want to install it for some reason, you can use the JMP Custom module to create this icon.
After downloading and installing JMP Custom, go to the Module management section > New > JMP Custom

Here, enter the parameters as below:
HTML:
<a href="tel:911" class="pulse"><i class="fas fa-phone fa-2x"></i></a>
CSS:
@import url("https://cdnjs.cloudflare.com/ajax/libs/font-awesome/5.7.2/css/all.min.css");
.pulse i{color:#fff}
.pulse{height:100px;width:100px;background-color:orange;border-radius:50%;display:flex;justify-content:center;align-items:center;position:fixed;bottom:50px;right:50px;z-index:999}
.pulse:hover{text-decoration:none;}
.pulse::before{content:"";position:absolute;border:1px solid orange;width:calc(100% + 40px);height:calc(100% + 40px);border-radius:50%;animation:pulse 1s linear infinite}
.pulse::after{content:"";position:absolute;border:1px solid ORANGE;width:calc(100% + 40px);height:calc(100% + 40px);border-radius:50%;animation:pulse 1s linear infinite;animation-delay:.3s}
@keyframes pulse {
0%{transform:scale(0.5);opacity:0}
50%{transform:scale(1);opacity:1}
100%{transform:scale(1.3);opacity:0}
}
In the HTML field, replace "911" with your phone number.
In the CSS field, replace "orange" with your preferred color (HEX/RGB). If your site already has Font Awesome built-in, you can remove the line of code:
@import url("https://cdnjs.cloudflare.com/ajax/libs/font-awesome/5.7.2/css/all.min.css");
I migrated about a thousand items with attachments from K2 using your tool and attachments plugin. I initially did this on a test account. Everything worked fine over there. The migrated article attachments worked fine. Then I backed it all up and moved it to my live domain. Now none of the attachments load. All I get is Exception File Not Found and I can't figure out where to look. Turning on error reporting and debug don't tell me anything. I am guessing the old files were not moved during the migration correct? Or how does that all work? I still have all the original folders in the original places as far as I can tell.
An error has occurred. 0 implode(): Argument #2 ($array) must be of type ?array, string given

Any idea what's causing this?
