Please [login through FTP](https://www.wpbeginner.com/beginners-guide/how-to-use-ftp-to-upload-files-to-wordpress-for-beginners/) and go to **wp-content/plugins/wpforms-lite**. Download the entire directory for backup purposes then delete it. Once deleted log back in to your admin area and go to **WP Admin > Plugins > Add New** then search and reinstall WPForms. * In case the issue persists,could you please try using the steps in WPBeginner’s detailed guide on [troubleshooting WordPress](https://www.wpbeginner.com/beginners-guide/beginners-guide-to-troubleshooting-wordpress-errors-step-by-step/) to see if it helps resolve the issue? * [lauramelos](https://wordpress.org/support/users/lauramelos/) * (@lauramelos) * [5 years, 9 months ago](https://wordpress.org/support/topic/fatal-error-caused-by-wpforms/#post-13409262) * Hey, we are having the same error, and we could identify that it appears after update WooCommerce to it last versión (4.5.2), on PHP 7.3. (it works in older versions of php) Is there any chance that you can check it? * [Jade](https://wordpress.org/support/users/jadeam/) * (@jadeam) * [5 years, 8 months ago](https://wordpress.org/support/topic/fatal-error-caused-by-wpforms/#post-13434575) * Hello [@lauramelos](https://wordpress.org/support/users/lauramelos/), * It appears that `iconv()` function is not available in your PHP installation which might be the reason why you’re getting that error message. In order to resolve the issue you’re facing you can get in touch with your hosting provider to install/enable the `iconv` and `mbstring` PHP extensions. * Thank you. * [Jade](https://wordpress.org/support/users/jadeam/) * (@jadeam) * [5 years, 8 months ago](https://wordpress.org/support/topic/fatal-error-caused-by-wpforms/#post-13464379) * Hi [@lauramelos](https://wordpress.org/support/users/lauramelos/) and [@jhimross](https://wordpress.org/support/users/jhimross/), * We haven’t heard back from you in about a week, so I’m going to go ahead and close this thread for now. But if you’d like us to assist further, please feel welcome to continue the conversation. * Thanks! * [lauramelos](https://wordpress.org/support/users/lauramelos/) * (@lauramelos) * [5 years, 8 months ago](https://wordpress.org/support/topic/fatal-error-caused-by-wpforms/#post-13464552) * Hey [@jadeam](https://wordpress.org/support/users/jadeam/), will try your suggestion. I wonder why it works before update woocommerce in same php env?. I’m sorry I missed your previous comment. * [lauramelos](https://wordpress.org/support/users/lauramelos/) * (@lauramelos) * [5 years, 8 months ago](https://wordpress.org/support/topic/fatal-error-caused-by-wpforms/#post-13464592) * I’ve just checked php info and both modules are installed and enabled. * [submid](https://wordpress.org/support/users/submid/) * (@submid) * [5 years, 8 months ago](https://wordpress.org/support/topic/fatal-error-caused-by-wpforms/#post-13521897) * [@jadeam](https://wordpress.org/support/users/jadeam/), similar error, iconv and mbstring are included * Warning: require_once(/home/u291857535/domains/59gears.hostingerapp.com/public_html/ wp-content/plugins/wpforms-lite/vendor/woocommerce/action-scheduler/action-scheduler. php): failed to open stream: No such file or directory in /home/u291857535/domains/ 59gears.hostingerapp.com/public_html/wp-content/plugins/wpforms-lite/src/WPForms. php on line 267 * Fatal error: require_once(): Failed opening required ‘/home/u291857535/domains/ 59gears.hostingerapp.com/public_html/wp-content/plugins/wpforms-lite/vendor/woocommerce/ action-scheduler/action-scheduler.php’ (include_path=’.:/opt/alt/php74/usr/share/ pear’) in /home/u291857535/domains/59gears.hostingerapp.com/public_html/wp-content/ plugins/wpforms-lite/src/WPForms.php on line 267 - This reply was modified 5 years, 8 months ago by [submid](https://wordpress.org/support/users/submid/). * [Jade](https://wordpress.org/support/users/jadeam/) * (@jadeam) * [5 years, 8 months ago](https://wordpress.org/support/topic/fatal-error-caused-by-wpforms/#post-13537986) * Hello [@lauramelos](https://wordpress.org/support/users/lauramelos/), * Can you please create a new post and include the specific error messages you are getting as it might not be the same issue as the original poster of this post.
