Unable to login in to WordPress wp-admin caused by Invisible reCaptcha plugin

March 22, 2018/0 Comments/in WordPress/by Stefan Helander

Being unable to login to your WordPress site, the first step is to follow this guide.

In a client case, none of the suggested steps helped and we were still locked out. It turned out that the plugin causing the lockout (error message invalid username or password) was Invisible reCaptcha.

It is possible to enable the settings for Enable Login Form protection even though the Site and Secret Keys are empty in the Settings tab in the plugin.

After logging out, it will not be possible to login again and no error message is indicating the problem is caused by the Invisible reCaptcha plugin. This must be considered a bug.

The solution is to remove wp-content/plugins/invisiblerecaptcha using FTP, then login and reinstall the plugin and configure Site and Secret Keys.

WordPress insert image/video/music problem caused by plugin

August 16, 2010/0 Comments/in Linux/FreeBSD/by Stefan Helander

When writing a post in WordPress, and you press Upload/Insert buttons to insert images, video, music or other media you can run into a problem where a popup displaying “Are you sure you want to do this?” is showing instead of the normal insert screen. The problem is described here. As mentioned in the posts, it is caused by some plugin. This can be hard to guess as the plugin in question might have nothing to do with writing and posting articles.

I ran into this problem using the latest WordPress 3.0.1. The plugin that was causing trouble for me was WP-ContactForm. By disabling it, it was possible to insert images in the posts again.

If you experience this problem, try disabling all plugins. If inserting images now works, try enabling the plugins one by one to figure out which one is causing the trouble.

phplist problem with local UTF-8-characters in subject line

June 14, 2010/1 Comment/in Linux/FreeBSD/by Stefan Helander

phplist is a popular software for sending newsletter to large lists of recievers. It has a large number of features which I will not go into depth here. For more information about what phplist can do – visit the phplist homepage.

If you are experiencing problems when you are sending a newsletter containing local characters, like the Swedish Å, Ä and Ö in the subject line, the most probable reason is that administration web pages are rendered in a character set different from the one used in the newsletter.

The following solution is assuming that you are running phplist on a Linux host.
