# Fatal error: Call to undefined function get_current_screen()

 * [13 years, 1 month ago](https://wordpress.org/support/topic/fatal-error-call-to-undefined-function-get_current_screen-1/)
 * I have a new WP install. 62 different pages, a little blog distributed around
   based on category. I’ve installed the e-commerce plug-in, added a few products.
   Still testing…
 * I keep everything in it up-to-date, checking for updates at least twice daily.
   I’m hosted on Dreamhost.
 * I haven’t yet gone live with the site (it’s filled with Latin text right now)
   because there is a weird error I keep getting.
 * Error #1:
 * 1. In the Dashboard, I click [Appearance] >> [Edit CSS]
    2. In the CSS window,
   I make a change, such as **p {color:pink;}** 3. I click [Save Stylesheet] 4. 
   I receive an error message that reads: **Fatal error: Call to undefined function
   get_current_screen() in /home/edwardmartiniii/testy.hellbendermedia.com/wp-content/
   plugins/wp-e-commerce/wpsc-admin/includes/product-functions.php on line 23** 
   5. So, I click the BACK button on my browser, and once again click [Appearance]
   >> [Edit CSS] 6. My change is not present. 7. So, I open the described file “
   product-functions.php”. Line #23 reads: $current_screen = get_current_screen();
   8. Meaning I can’t edit the CSS programmatically. I don’t know what this function
   is SUPPOSED to be doing, and I don’t know why editing the CSS calls a function
   in the e-commerce module anyway. 9. Troubleshooting suggestions welcome! I could
   MANUALLY edit the CSS file and then upload it, but I’m afraid any changes I make
   will simply be lost in the next update.
 * Thanks!
 * Edward

 * The function get_current_screen() is included since WP 3.1, are you using old
   WP version?

 * Sorry — I forgot to add that bit.
 * I’m using WordPress 3.5.1.
 * I check for updates to WP and to all plug-ins roughly twice a day.

 * Can’t find any clues then, probably only the
 * wp-e-commerce
 * developer can help you.

 * Dang! That got me thinking.
 * I deactivated the e-commerce plug-in and tried to edit the CSS. Worked great.
 * Reactivated the e-commerce plug-in.
 * Tried again. Fail condition.
 * So this much I know — the problem is probably in the e-commerce module (or at
   least manifests there).
 * I CAN change my CSS, but I have to temporarily bring the e-commerce plug-in down.
 * It’s hacky, but I’m back in business at least.

 * Same issue here. Would you advise using a different e-commerce plugin? If so,
   which one?

 * “Same issue here. Would you advise using a different e-commerce plugin? If so,

 * I got tired of the hack.
 * I dumped e-commerce and instead installed MarketPress and bought a subscription
   to the company’s support system. I regret NOTHING!
 * I now use several of their plug-ins. Three thumbs up!

    1. Open ** “wp-content/plugins/wp-e-commerce/wpsc-admin/admin.php”**
    2. After Line #26: Add ** “require_once(ABSPATH . ‘wp-admin/includes/screen.php’);”**
    3. Save your changes… and see if bug still exists.
