If you’re using this WordPress plugin to show Instagram images gallery on your site, and you noticed that images don’t show anymore, chances are, that this is due to deprecated PHP function ereg_replace. recently I upgraded my PHP version to 7.1 and this plugin stopped working. So, if you upgraded your PHP, this is almost certain the cause of problem. There is how to fix this.
Error log was showing this:
2017/02/11 11:31:40 [error] 18865#18865: *4616 FastCGI sent in stderr: "PHP message: PHP Fatal error: Uncaught Error: Call to undefined function ereg_replace() in /path/to/site/public_html/wp-content/plugins/alpine-photo-tile-for-instagram/gears/alpinebot-display.php:58
So, open alpinebot-display.php with your favorite text editor and go to line where error is – in this case 58. Just replace ereg_replace with preg_replace and it should work again.
Hope it hepls.
