There are hundreds of plugins. If you downloaded a plugin, try contacting the programmer (or debug the plugin yourself). If you created the plugin yourself, debug your code.
You can change your screen name by following this video: Change Name
Also, feel free to read the FAQ: Re: 2. How do I ask a question on the forums?
Please be aware that we cannot debug code that we cannot see. (you have not yet given us anything that we can debug.)
Also, the first thing we like to do is: prove that the bug exists. As such, you need to give us step-by-step instructions on how to reproduce the bug.. There is a trick.
For some situations, in help to reproduce the bug on http://apex.oracle.com web site. You'll need to provide workspace name, developer's account credentials,, application id, and page number. (and steps to reproduce the bug)
If this is a 3rd party plugin, a link to the site (or GitHub repository) would be very helpful.
Many thanks, and welcome to the forum
I'm new in programming using oracle apex can yo tell me how i can debug the plugin.
thank you in advance for your cooperation.
When you run your application from Apex Builder, you can run it in debug mode:
Hopefully the programmer of the plugin included some debug info in the code.
