Problem with sidebars and plugins

Hi, I am using the Evolution Pro Theme with a child theme. It has been working perfectly until I tried to add a couple of plugins. Both of the plugins are having problems displaying the sidebars. I have installed a photo gallery plugin and it is causing the sidebar to be displayed at the bottom of the page below the content. I have used this plugin on a couple of other sites with other themes and have not had this issue. I have completely removed the <?php get_sidebar() ?> code from the plugin, but the sidebar is still appearing. You can see this here: http://bayoucityflyersrc.com/index.php/gallery/dsma-powered-rc-area/ The page is full-width and the sidebar is being displayed at the bottom below the content. The other plugin is WPAdverts which adds a bulletin board to the site. This plugin is randomly displaying sidebars on the various bulletin board pages. I have been working with the plugin developer and he has tried some work arounds with the plugin code, but I am still having the issue that the selected sidebar is not being displayed, rather a random one is displaying. He has said that there may be something irregular with the sidebar set up of the theme. I believe that both of these problems may be because of incompatibility with the theme, but have not had a problem with these plugins on other sites with other themes. Is there something that you can do to help with the compatibility and sidebar issues?
