If the problem persists, try to remove and re-install our plugin. * Please, keep us posted, if you keep having troubles we might need to report this back to the developers. * Thread Starter [alexandrugabrieliacob](https://wordpress.org/support/users/alexandrugabrieliacob/) * (@alexandrugabrieliacob) * [6 years, 10 months ago](https://wordpress.org/support/topic/compilation-failed-4/#post-11805755) * Yeah…. same solutions everytime …”deactivate all plugins, try reinstalling nextgen”… I’ve fixed today for my php 7.3.7 version: * simple_html_dom.php:#1384 * ..the regex for preg_match should like like this “/^[\w\-:]+$/” not “/^[\w-:] +$/” * Thank you for your support.

If you have some time, we would love to have a second look. * We may need to deactivate plugins and switch the theme while troubleshooting temporarily. Would you feel OK with that?. If so, please report this issue as a bug using this form: [https://www.imagely.com/report-bug/](https://www.imagely.com/report-bug/). Be as specific as possible and let them know Gaby referred you. * Note: do not forget to include this forum’s link. Many thanks!
