1) Is there some CSS for increasing the size of the bootstrap slider button?
Please post your website url to your bootstrap slider, we will try to provide a solution.
2) Can I increase the size of the short code button?
If you are referring to the Theme4Press shortcode creator button, Sorry we cannot increase this button size.
If you are referring to size of shortcode generated button, please post your website url to your buttons.
3) When attempting to insert shortcode for blog I get the following error, “Warning: Invalid argument supplied for foreach() in /home/myadminname/public_html/wp-content/plugins/t4p-core/tinymce/shortcodes.class.php on line 65”
In your wp-config.php, please turn WP_DEBUG off. It’s a PHP warning, not an error. In the event of a PHP fatal error, you will only see a blank page.
