# Error: Call to Undefined Function

 * It seems that every week my entire site goes down to this plugin. The error code
   down below is what I receive.
 * `Fatal error: Call to undefined function portfolio_gallery_isset_table_column()
   in /home1/aidan/public_html/wp-content/plugins/portfolio-gallery/includes/class-
   portfolio-gallery-install.php on line 39`
 * Removing the plugin and re-installing will allow the site to work for about a
   week, after which it will crash without fail. Is there any real solution to this
   problem other than telling us to deactivate/reactivate this plugin?
 * Thank you.

 * Dear [@aidanhockey5](https://wordpress.org/support/users/aidanhockey5/) we apologies
   for the issue.
    Our team works on the solutions everyday.
 * But the plugin may not crash by itself probably every week you make updates. 
   Just try not to make updates for some time.

 * For anybody else that has this issue, I’ve just attempted a temporary solution:
 * 1) I went through via FTP to my sites’ plugins folder (/wpcontent/plugins) and
   deleted the portfolio gallery folder. Your portfolio’s will remain safe, but 
   you will have to re-install the plugin.
    2) Once the portfolio plugin was re-
   installed, your portfolios should automatically come back and the site should
   start working again. 3) Finally, I went into my plugins page on WordPress and
   went to the “Edit” link under Portfolio.
 * -In “portfolio-gallery.php,” you should see a version number in the header area.
   
   For example:
 *     ```
       Plugin Name: Portfolio
       Plugin URI: http://huge-it.com/portfolio-gallery
       Description: Portfolio Gallery is a great plugin for adding specialized portfolio galleriey, video portfolio gallery of just a gallery with single images.
       Version: 99.99.99
       Author: Huge IT
       Author URI: http://huge-it.com/
       License: GNU/GPLv3 http://www.gnu.org/licenses/gpl-3.0.html
       Text Domain: portfolio-gallery
       Domain Path: /languages
       ```
   
 * Notice how I changed my version number to something huge, like 99.99.99? This
   will hopefully prevent the plugin from auto-updating to a new version. This seems
   like a really hacky work around. Really would like to see this fixed officially.
   I’ll reply to this thread again if this workaround ends up failing.

 * Thank you for this information. Avoiding the updates is helpful for those who
   have set the auto update, but if you run manual updates then just don’t click
   on update button till in changelog we announce about fixing of this issue.
 * But if you very much need to make updates, then following the description below
   delete and install the plugin again
 * Thank you for understanding and cooperation.
