Plugin Troubleshooting Guide
This is my profile page on WordPress.org. I'm a WordPress
plugin developer, and also engaged in many other activities in the community.
Fukuoka, Japan I'm from Fukuoka, Japan. Fukuoka is known as
the birthplace of Wapuu.
This is the world's first Wapuu cake. We made it
for WordCamp Fukuoka 2011.
This is Contact Form 7's plugin page on WordPress.org.
I have been maintaining this plugin for more than 10 years.
According to BuiltWith.com, Contact Form 7 has a 71% market
share in the “Feedback Forms and Surveys on the Entire Internet" category.
Because of its popularity, I constantly receive a lot of
support requests. Today, I tell you the secret of troubleshooting.
Troubleshooting in General
Troubles caused by WordPress core are very rare.
Most troubles are caused by its plugins and themes.
To find out which plugin is the culprit: •Try
deactivating all plugins at one time. •If the problem disappears, re-activate them one by one.
If you click on the "delete" link, the plugin will
try to wipe out all data related to it. If this is inconvenient for you, access the server via FTP and delete the plugin files manually. Be careful when you delete plugins
Cache might be connected to the trouble. Try
deleting all browser cache and page cache, and check to see if the behavior changes.
Some troubles are seen only when you are logged-in, or
when you are logged-out, and this information will be a useful hint to troubleshoot in many cases.
Getting Support from Community-based Forums
Don't send a direct message to developers to get
support. Many developers don't like to answer questions privately. Use public support forums instead.
Each plugin has a dedicated support forum on WordPress.org.
This screenshot image points to the "Support" link on a plugin page.
This is an example of a support forum for a
plugin.
At the bottom of the plugin support forum, there is
a form to create a new topic. Detailed information is necessary to get helpful support.
WP.org Support Forums are: •Volunteer-based Be polite and kind to
others. •Public forums Providing information publicly is needed.
Before using support forums, look through the Forum Guidelines
and FAQ on WordPress.org. Let's have a look at some of the topics.
Do Not Spam Don't do spammy activities on the forum.
Don't post comments for the purpose of promoting something. If you do that, you'll get a penalty.
No "Bump" Some users just post "Bump" with an attempt
to get attention for their forum posts. This will never work, and is prohibited.
No "Me Too" Don't hijack others' topics with a "Me
too" comment. It is rude to the original poster, and your problem is different from theirs in almost all cases.
Do Not Offer to Pay for Help Do Not Offer
to Work For Hire WordPress.org support forums are not a place to look for jobs or paid services.
If you are looking for jobs or paid services, use
jobs.wordpress.net instead.
Do Not Post About Commercial Products Posting about commercial
products is prohibited. The responsibility of support lies with the vendor of the product.
Do Not Post Sensitive Information Login ID and password,
email addresses, or any kind of keys or secrets should not be posted.
There are many other topics in the guidelines and FAQ.
Read them carefully and be a good forum participant.
Preventing Troubles from Happening
You can avoid troubles if you use trustworthy plugins only
✓ hosted on wordpress.org (100% GPL and free) ✓ maintained by experienced developers ✓ updated to the latest WordPress versions
Feedback is the most important factor in maintaining a quality
of software. Most commercial plugin and theme vendors can't get enough feedback in quality and quantity. Avoid them if you want to avoid troubles.
Thank you!
