Can you switch to a default theme like ` Rookie` or `TwentSeventeen` and try to reactivate SportsPress? * Thanks, Savvas * Thread Starter [iconMatrix](https://wordpress.org/support/users/chevyfixr/) * (@chevyfixr) * [7 years, 6 months ago](https://wordpress.org/support/topic/fatal-error-cannot-redeclare-class-sp_admin/#post-11025444) * That’s too bad. I set my site up using Storefront by woocommerce. * Thanks for the info * Plugin Contributor [Savvas](https://wordpress.org/support/users/savvasha/) * (@savvasha) * [7 years, 6 months ago](https://wordpress.org/support/topic/fatal-error-cannot-redeclare-class-sp_admin/#post-11025688) * If the problem was solved when you switched to a default theme, then you should contact the theme developer to tune their code. If the problem was still there, then some other plugin may occur this conflict. Try to disable all plugins except SportSpress. Then enable one by one to identify the “problematic” one 😉 * Thanks, Savvas * Thread Starter [iconMatrix](https://wordpress.org/support/users/chevyfixr/) * (@chevyfixr) * [7 years, 6 months ago](https://wordpress.org/support/topic/fatal-error-cannot-redeclare-class-sp_admin/#post-11028374) * After deleting then activating each plugin until a problem happened, I found that Storefront Powerpack was the offending plugin.

You should disclaim it that it will not work with Woocommerce Storefront that has the Woocommerce Powerpack plugin installed, to save another developer from wasting their time. [https://www.themeboy.com/sportspress-extensions/](https://www.themeboy.com/sportspress-extensions/) * Thanks * Plugin Contributor [Savvas](https://wordpress.org/support/users/savvasha/) * (@savvasha) * [7 years, 6 months ago](https://wordpress.org/support/topic/fatal-error-cannot-redeclare-class-sp_admin/#post-11033764) * Hi [@chevyfixr](https://wordpress.org/support/users/chevyfixr/), * SportsPress is fully compatible with the WooCommerce plugin. * For some reason the Developers of Storefront Powerpack didn’t follow the “prefix rule” to avoid this type of conflicts. * WooCommerce plugin uses the prefix `wc_` and SportsPress plugin uses the prefix` sp_`. This is well described in [WordPress Plugin Developer Handbook](https://developer.wordpress.org/plugins/the-basics/best-practices/#prefix-everything). * Someone should expect that Storefront Powerpack would have chosen a prefix like` wcsp_` (similar to `wc_` their “parent” plugin WooCommerce uses). * Anyway, as I can understand, Storefront Powerpack is a paid plugin, while SportsPress is a [free opensource project](https://github.com/ThemeBoy/SportsPress). If the Powerpack developers are not willing to change their code then you can fork SportsPress and make the appropriate changes you want. * If you have an active license for the SportsPress WooCommerse plugin then please come in contact with our Premium Support at [https://support.themeboy.com/](https://support.themeboy.com/). * Thanks, Savvas - This reply was modified 7 years, 6 months ago by [Savvas](https://wordpress.org/support/users/savvasha/).

In the meantime I’ll make a test site so I can look at and play with SportsPress * Thanks for your help * [Roch](https://wordpress.org/support/users/rochesterj/) * (@rochesterj) * [7 years, 6 months ago](https://wordpress.org/support/topic/fatal-error-cannot-redeclare-class-sp_admin/#post-11041480) * You’re most welcome! * Let us know if you need anything else.
