How to uninstall or reinstall the Fast Secure Contact Form WordPress plugin

The auto install/update functions are part of the core WordPress files. If your install/update fails there is nothing wrong with the plugin. Your server may be having trouble with resources such as low available memory or too high of a load demand. Or something random simply failed during the install/update. At this point, a manual uninstall / auto install might be the solution.

Sometimes the WordPress auto install or auto update function fails and the plugin is left in a state of non-functionality. In that case you will need to uninstall and reinstall it. First try a manual uninstall, then do the auto install. If the auto install is not working then try a manual install.

Backup your Forms and Settings:
You can backup/restore your Fast Secure Contact Form forms and settings using a tool on the contact form edit page.

Auto Uninstall:
On the plugins admin page, find Fast Secure Contact Form and click “Deactivate”.
When the plugin is deactivated, the forms and settings are still saved in the database.
When just reinstalling: DO NOT DELETE the plugin from the WP admin page or the forms and settings get deleted from the WP database.
To completely uninstall: find Fast Secure Contact Form on the plugins page and click “Deactivate”, then click “Delete”, a warning will show up telling you that all plugin files and settings WILL BE DELETED PERMANENTLY. Make your choice.

Manual Uninstall:
If the form still works, you should backup/restore your Fast Secure Contact Form forms and settings using a tool on the contact form settings page. The forms and settings are not stored in the plugin folders, so this does not require a backup if you follow instructions correctly. But DO NOT delete the plugin from the WP admin page or the forms and settings WILL PERMANENTLY get deleted from the WP database.
FTP to the server and delete this folder: /si-contact-form/
the folder is found in /wp-content/plugins/
When the plugin folder is deleted, the forms and settings are still saved in the database.

Auto Install:
On the plugins admin page, click “Add New”, search plugins for “Fast Secure Contact Form”.
When you see “Fast Secure Contact Form” in the search results, click “Install”. The plugin will be automatically downloaded, installed and then you can click “Activate”. The plugin will now be activated.

Manual Install:
Download the Fast Secure Contact Form zip file:
http://downloads.wordpress.org/plugin/si-contact-form.zip
Unzip the file on your computer.
Use a FTP program such as FileZilla to connect to your web server .
FTP File Transfer this folder this folder: /si-contact-form/ from your downloaded files to the folder on your server: /wp-content/plugins/
On the plugins admin page, find “Fast Secure Contact Form” and click “Activate”. The plugin will now be activated.

I have stuck files that will not delete, what do I do?
Sometimes a web server will have stuck files that you cannot delete by FTP, this could be caused by a locked file, improper permissions or group ownership. If this is your own server, try restarting it, then see if you are able to delete the files now. If it is a server on a web hosting account, first try a Manual Install (replace all the plugin files by FTP, then reactivate). If that still does not work, then make a trouble ticket with your web host to have them remove the files/folder that you were not able to delete. Now you can install again.

Some users report the update fails with a message that the update process was unable to delete old files. “When I looked in wp-content/plugins/si-contact-form/, I saw that the captcha/ directory and five .ttf files within it remained.” The problem is caused by a PHP bug: “.ttf files have stuck open file handles” is a bug in PHP itself but only on windows servers. The bug was reported in 2003 on bugs.php.net and has never been fixed. If you restart the server, the files are unlocked and can be deleted, then you can reinstall the plugin.

My WordPress is broken now, what do I do?
Sorry you are having trouble. The auto install/update functions are part of the core WordPress files. If your install/update fails there is nothing wrong with the plugin. Your server may be having trouble with resources such as low available memory or too high of a load demand. Or something random simply failed during the install/update. I do not have an identifiable cause or solution to the problem. First, try the Manual Uninstall of the plugin as noted above.

If you tried all of the above steps and your WordPress is still broken, you may need to repair your WordPress installation. That is beyond my area of support, but if it happened to me, I would backup my WP files and database, then upload by FTP and replace all the WordPress files with the latest ones from the current download package. Never try this without first backing up though.

Why does the WordPress Auto Upgrade for this plugin ask for FTP Login?
The auto install/update functions are part of the core WordPress files. My plugin does contain any install/update code programming. On some servers WordPress itself, will ask for FTP login. If your host is running suPHP, or WordPress can modify the plugin files directly with ease, then FTP details are never asked for. However, if it cannot modify the plugin files, it will request FTP details to connect and perform the upgrade.
