 * Hi,
    Please test if development version at [https://downloads.wordpress.org/plugin/apply-online.zip](https://downloads.wordpress.org/plugin/apply-online.zip)
   fixes this issues for you.
 * I look froward to hear from you.

 * Yes the development version is working great with no errors, thanks for the speedy
   fix.
 * On a side note, would it be possible for you to add an aol class name to the 
   shortcode elements?
 * Eg.
 * `<div class="panel panel-default">`
 * could maybe do with `aol-panel` adding in there too as it’s not as generic as
   just panel and can be used to identify the plugin components specifically while
   customizing styles.

 * That’s good.
 * We are planning another minor release which will be available in a day or two&
   will add a plugin specific HTML wrapper e.g. aol-archive for better control over
   styling. Thank you for your suggestion.
 * Please consider writing a review for this plugin at [https://wordpress.org/support/plugin/apply-online/reviews/](https://wordpress.org/support/plugin/apply-online/reviews/).
 * Best Regards.
