 * When trying to activate the plugin on WP 4.2 I get this error.
 *     ```
       Plugin could not be activated because it triggered a fatal error.
   
       Warning: exec() [function.exec]: Unable to fork [echo VERIFY] in /wp-content/plugins/pdf-image-generator/pdf-image-generator.php on line 14
       ```
   
 * It seemed to be working alright with the previous version of WP.

 * Hi ferne97.
 * It may be specific problem of your systems. Some hosting services disable exec
   command for security reasons.
 * Anyway, I updated version and changed the way to check exec command in an activation.
   I hope it helps you.
 * Thank you.

 * I am unfortunately having the same problem. Tried to activate it 3 times but 
   it just won’t let me. Maybe I will try gain in a couple months.
