You can confirm this by going to the Facebook Sharing Debugger. If this is the case, click the “Scrape” button to force Facebook to refresh its cache. Problem solved.

Font Awesome Icons won’t appear after WordPress domain change

I migrated my site from www.domain1.com to www.domain2.com and afterwards had problems with the Font Awesome icons appearing. The fix (for me, at least) was to use the Search & Replace plugin and replace all instances of domain1.com to domain2.com in the database. Just figured I’d share the fix since I didn’t see it out there anywhere.

For a while, I was just getting a PHP white screen with no information on why Zebra Forms was not working. I checked permissions and all that. Nothing helped. I turned on error reporting, and this helped identify the problem. To do this, create a .htaccess file in the same directory as your PHP file, and in it include: php_flag display_errors 1 This will allow you to see the debug output. I was getting the following error output: Warning: Cannot...

We had previously upgraded our experiment from PST E-Prime 1.x to 2.0 without incident. However, when I tried to get the application running on E-Prime 2.0 SP1 on a Windows 8.1 machine, I received a lot of design-time error messages. For example, in a dialog that appeared when I tried to run the application, I was told that Windows 8 requires FlippingEnabled to be turned on. So I went to the Experiment Properties and turned this on. After, when trying...

I was using two input fields positioned next to one another — one above the other. I had added :focus styling with a box-shadow in CSS so that input boxes would glow with a blue border whenever they received the focus. However, the first element’s box-shadow was always being cut off at the bottom by the second element. I discovered that this was because later elements are placed on top of earlier elements vertically. I tried to fix this by...
