If you are getting a 404 error when you are accessing the posts, you need to reset your permalinks. Refresh the permalinks by going to Settings->Permalinks and set the default permalinks of the site and save. After that use a different permalink name and press the save button one more time.
If you have any of our latest themes - you have the option to change the slug for the custom posts (video, gallery, event) and for their category pages. This can be done by accessing the General tab of the theme options panel, the options should be placed at the end of the list.
First of all, you'll need to change the name in the inputs and click the save button. After you new settings with the new slugs are saved, you will need to reset your permalinks. In order to do that you will need to go to the WordPress Dashboard Settings-> Permalinks tab. There, you need to click the save button. No need to change any of the settings for the permalinks, just click the save button.
If everything is done right, you will get new URLs and no 404 pages will appear. If you get the 404 error after this, try to check again your settings and reset the permalinks again. Also, clearing your browser cache could help.
Some of our themes have the option to change permalinks slugs in the theme options panel. It might happen that when you change any, after you try to access one of them you get 404 page not found errors. This is because you need to reset your permalinks as the structure. Nothing very hard to do here, we do have a tutorial on this: http://support.touchsize.com/knowledgebase/Gallery-posts-or-videos-custom-posts-are-not-working-39.html
After you reset them, try to access any. They should work nicely.
WP_DEBUG is a PHP constant (a permanent global variable) that can be used to trigger the "debug" mode throughout WordPress. It is assumed to be false by default and is usually set to true in the wp-config.php file on development copies of WordPress.
In order to make your WordPress installation show the errors you are getting from a theme or plugin, you can activate it. Note that this is not recommended to live websites as users will see the errors, but in case you need to debug your website and see why it is crashing or what could be causing the issue, the first step would be to check the debug mode.
You can be asked by some of our representatives to activate the debug, as there are cases when the support team can't really guess what could be the problem.
In order to do that, you'll have to connect to your server via FTP, edit the wp-config.php file there and find the line:
define( 'WP_DEBUG', false );and basically change the "false" declaration to true.
