I just felt so much fear! While I was giving the final touches to the blog so that it is ready for its launch on January 1st, girlknowstech.com has become down. Error 500, and sometimes the famous white page of PHP. Do I need to tell you how disappointed I was? If you have the same problem right now, don’t be afraid, maybe I can help you fix the problem!
For my part, I had this error while I was modifying my file “functions.php” in WordPress: Appearance> Editor> Functions.php. What I did not know is that when we modify our file functions there, it is not the one at the root that we modify, but the theme’s functions.php!
