Update of captcha-Plugin does not work

My wordpress installation suggested the update of a plugin for captcha, but it actually failed with an error message mentioning permissions and the files „captcha/cache/index.php“ and „captcha/cache/.htaccess“.
What did help:
In the directory of the wordpress-installation go to
Then delete the files index.php and .htaccess
Make a backup of them outside of the wordpress installation before deleting them.
Run update again.
This time it should work.
This is what I was able to do with my wordpress installations.
I am running 4.4.2–de_DE.

So it worked for me, that’s all I can say about this issue.

Code examples in WordPress

When writing word press articles and including example code with <code>, the leading spaces are discarded when the article is displayed and without indention code looks weird and unreadable.

A way to bypass this is to transform tabs to spaces, and then replace all spaces by no-break-spaces (unicode 0x00A0). Then the indention remains intact. Direct copy paste from the blog to an editor or IDE will not be resulting in runnable code. But for non trivial examples I would recommend to put the code on github and add a link to the article. Code sniplets in articles should be mostly for human readers.

Update of WordPress


The update of WordPress and its Plugins did not really work.

A small change helped a lot:

In .htaccess put the following line to the beginning of the file:

AddHandler php56-cgi .php

Then all updates seemed to work fine.

Maybe this helps others observing the same problem.

Comment Functionality

The comment function does not seem to work after some software upgrades.
It is necessary to check write permissions on the directory /wp-content/plugins/si-captcha-for-wordpress/captcha/cache, then it will work again.
So you can write comments again, I will only reject spam.
