I am fed up the error occurring on my screen that is related to the optimization in the Facebook. The error stated “An error occurred. Please try again later”. What would be the cause of this issue? I am even clicking on the login button but no response has occurred. Please post some guide to resolve this issue. Thank you!
Actually this type of problem occurs for the error of your website script. You need to fix your code in that script which you already uses for the log in button. You can get enough idea regarding that issue in facebook developer page. There have practical briefing with exact tutorial in https://www.facebook.com/help/ that page. I hope if you read the details tutorial there, you could not face this type of error again.
In your question, you were not added you script which you used in your website. So I can not help you now to fix you error code in script. But I can give you actual suggestion to resolve your problem.
If that problem is always happening whenever you access Facebook, see how fast your internet connection is. Visit Speedtest.net and click “BEGIN TEST” to test how fast your internet connection is. At the end of the test, you should see something like this.
The value under “PING” is your current ping rate. It measures how fast you can connect to a server in milliseconds. The smaller the value, the faster your connection is. My current ping rate is high, 100 ms, which means I have a slow connection. “DOWNLOAD SPEED” and “UPLOAD SPEED” indicates your current download and upload speeds, respectively.
After measuring your speed, compare it with your internet plan’s advertised speed if it’s any way nearer or far too slow. If your connection is slow and you are connected to a router, try resetting your router. If your router has a power button, press it to turn it off then unplug it from the power for about 10 to 20 seconds.
Press any button on the router to further drain any leftover power. After this, plug the router back to the power and turn it on. When the router is ready, try connecting again and see if it works. If there’s no change, try using a different browser like if you are using Mozilla Firefox, try using Google Chrome or the Opera browser.
