fixing an error - repost

Just checking to see if you're available for what should be? a quick fix I'm guessing with your experience. I have some scripts that were running fine on a server, and then just stopped working. "Fatal error: Call to a member function find() on a non-object in /home/..../public_html/pp/.....php on line 37" The code on line 37 is: foreach($html->find('img') as $element) I had a coder look at it but he says he thinks it's the server. Hosting support says it's a code issue. It doesn't make sense that it was working fine, and then just started having errors, if no changes to the code or server were made. We didn't make any code changes, support said there were no server changes. The last time I know it was working correctly was Monday 2:29 pm est. We installed on another server, and it worked, then stopped for an hour maybe, then worked again and still is, but we have more scripts that won't fit on that server, so we need another one that the scripts work on. We tried a 3rd server for the rest of the scripts, it worked when doing a couple manual tests, but then didn't work anymore and still won't, showing the error above. All 3 servers are from the same hosting company. The scripts are ran by a cron job. They check a web page on another site for new files added, and send an alert email to us when a new one is found. The scripts use proxies, but the proxies seem ok. The 5 lines of code following line 37: { $image = 'https://...../...../'.$element->src; $image1 = substr($image,70); //echo $image1; } The top 5 lines of one of the scripts: <?php set_time_limit(0); require ("[login to view URL]"); require '[login to view URL]'; require_once('[login to view URL]'); I don't know if the server logs could give some info on what happened, or what else. Thanks
