# Can’t Save post When Adding [Expiry Date] Shortcode

 * I’m using [this](https://simple-membership-plugin.com/simple-membership-addon-show-member-info/)
   plugin to retrieve data from member. The problem is when adding the shortcode`[
   swpm_show_member_info column="expiry_date"]`, I couldn’t save the post/page. 
   it says “_Updating failed_” with red bar at the top of the editor. When I close
   the editor and open the page again, I get this critical error: “_There has been
   a critical error on this website._“.
 * For record, I’m using the latest version of both Simple Membership (Version 4.1.2)
   and SWPM Show Member Info (Version 1.9) plugins.

 * Already done that. I disabled all plugin and switch the theme back to default,
   but the problem persisted. Any chance this might be caused by the PHP version?
   I’m using 8.0.17.

 * When you get a critical error, WP should send you an email with more details 
   of what the exact error is (it usually refers to some files, functions and lines
   of code). Also, that will be added to your server’s error_log file. Can you post
   the error message so I have some reference to check in the code?

 * Looks like the “subcript_period” field doesn’t have a valid value for this member(
   that you are testing with or viewing the page with.
 * Check the membership level of the member/user account that you are viewing the
   page with. most likely the admin user. Then edit that membership level and view
   the subscription duration value that you have set for that level. Does it have
   a valid value? What value is set for the “Access Duration” field for that membership
   level?

 * The error isn’t on the user front-end, but on the page editor of the admin dashboard.
   Despite the update appeared to be failed, the value of the `[expiry_date]` is
   still displayed correctly for all user on the front-end. It’s just that when 
   I try to edit the page again, the fatal error that I sent before will appear.

 * Perhaps this problem is on the instance I was using when installing WP, not the
   plugin. Thank you for helping anyway

 * Thank you. I understood that the error is when you update the post in the admin
   end. When you are updating post with a shortcode in it, there are some themes
   or plugins (example: page builder type plugins) that execute the shortcode still.
   So if your WP user that is editing the post also is connected to a member record(
   meaning you imported that wp user to our membership plugin), then it can throw
   that error if the membership level’s configuration is not as expected. It’s just
   one of the possibilities so I thought it’s best to check that.

 * I got it now, but still weird tho 🙁
 * My account is the only admin and the only editor. I don’t have this account registered
   as a member in the plugin. Also, my theme is really basic, just like skeleton
   template and no builder plugin installed — really sure I don’t have any function
   that can execute this shortcode on admin end. I’m not experiencing this issues
   on the classic editor but only on Gutenberg.
 * Since the shortcode is working just fine on member end, would be any update that
   instead of showing error and disable the post editor, it will execute a fallback
   like an empty value?

 * Just want to test one theory, can you please download a new copy of the addon(
   v2) from here and let me know if that one works better or not?
