Import doesn't fully complete

While things have been going great this past month, sadly I am coming across issues again today. We’ve successfully imported galleries of around the same size that we were doing when I had posted last month using the import folder feature after we upload our folders, even earlier today. However after a certain point, it just stopped working normally. We’re used to seeing the blank white page stay on the browser for a period of time before the percentage bar appears to generate all the thumbnails. After doing a number of galleries today with this, it decided to just hang on the blank page and never bring up that bar. Strangely enough, even though the process appears to just stop in the browser, the database is still being populated in the background. In checking the gallery on the backend, it eventually gets fully populated. But because the script stopped in the browser, we then have to generate thumbnails page by page in the edit gallery page. I’ve already jacked up variables in php.ini previously, and since we’re not importing anything bigger than previously, I’m not sure what else could be causing this, especially after working with no issues earlier today. My PHP settings can be seen at https://missdream.org/phpinfo.php , if you can provide any assistance, that would be greatly appreciated. Thanks!
