cannot install recaptcha plugin for multisite

Under the *super admin* menu.

there is no recaptcha on *super admin* menu.

I have tried several things like
– chmod 755 on mu-plugins
– chmod 777 -R wp-content (this is serious, nothing works now. now if i change mode -R to others also doesnt work at all. I have to now reinstall the wholething again.

Please help, how can i install recaptcha on wordpress Multiuser ?

Please confirm you did these steps:

2- Move the wp-recaptcha.php file out of the wp-recaptcha folder so that it is in /wp-content/mu-plugins
3- Now you should have /wp-content/mu-plugins/wp-recaptcha.php and /wp-content/mu-plugins/wp-recaptcha/

Yes, i confirmed i did that.

After that the whole site didnt work.
HTTP Error 500 (Internal Server Error): An unexpected condition was encountered while the server was attempting to fulfill the request.

Here is how the content looks like:

[root@ns1 mu-plugins]# pwd
/home/admin/domain.com/wp-content/mu-plugins
[root@ns1 mu-plugins]# ls -al
total 56
drwxr-xr-x 3 root root 4096 Dec 11 04:16 .
drwxr-xr-x 6 root root 4096 Dec 10 18:45 ..
drwxr-xr-x 2 root root 4096 Dec 11 04:16 wp-recaptcha
-rw-r–r– 1 root root 44556 Dec 11 04:16 wp-recaptcha.php

Deleting those files got the site working again. What went wrong ?

Im quite sure my site might not work with other mu-plugins.

Can you recommend a simple plugin to debug this issue ? some debugging method word help me solve this issue.

Thanks!

It;s an issue with your server.

Go in the repo, find any simple mu-related plugins that has one file and dump it in mu-plugins.

If it spazzes out again on you, you may need to ask your host what’s up.

I have migrated to cpanel instead of kloxo. Still it does not work.

If I did this:
2- Move the wp-recaptcha.php file out of the wp-recaptcha folder so that it is in /wp-content/mu-plugins
3- Now you should have /wp-content/mu-plugins/wp-recaptcha.php and /wp-content/mu-plugins/wp-recaptcha/

It will cause this:

Warning: require_once(/home/domain1/public_html/wp-content/mu-plugins/recaptchalib.php) [function.require-once]: failed to open stream: No such file or directory in /home/domain1/public_html/wp-content/mu-plugins/wp-recaptcha.php on line 45

Fatal error: require_once() [function.require]: Failed opening required ‘/home/domain1/public_html/wp-content/mu-plugins/recaptchalib.php’ (include_path=’.:/usr/lib/php:/usr/local/lib/php’) in /home/domain1/public_html/wp-content/mu-plugins/wp-recaptcha.php on line 45

mu-plugins is giving me the problem, but if i download into plugins directory, it ok.

I am really curious, how did you get recaptcha working with wordpress MU???

I found out where line 45 is in wp-recaptcha.php

if ($wpmu == 1)
require_once(dirname(__FILE__) . ‘/wp-recaptcha/recaptchalib.php’);
else
require_once(dirname(__FILE__) . ‘/recaptchalib.php’); <–line 45

so after printing out $wpmu, it appears to be 3.

Shouldnt it be 1 instead of 3? What is wrong ?

// WORDPRESS TYPE DETECTION
// WordPress MU settings – DON’T EDIT
// 0 – Regular WordPress installation
// 1 – WordPress MU Forced Activated
// 2 – WordPress MU Optional Activation
// 3 – WordPress MS Network Activated

After further debugging, I found out why in wp-recaptcha.php
first it sets to $wpmu = 1 but then it notice “is_multisite”, then it sets to 3.

My question is why you set to 3?? There is no installation instruction for 3? or should i be using 1? if so, how to ?

Thanks. Check the code below:

$wpmu = 0;

if (basename(dirname(__FILE__)) == “mu-plugins”) // forced activated
$wpmu = 1;
else if (basename(dirname(__FILE__)) == “plugins” && function_exists(‘is_site_admin’)) // optionally activated
$wpmu = 2;

if (function_exists(‘is_multisite’))
if (is_multisite())
$wpmu = 3;

drwxr-xr-x 2 root root 4096 Dec 11 04:16 wp-recaptcha
-rw-r--r-- 1 root root 44556 Dec 11 04:16 wp-recaptcha.php

I think part of your issue is that root is the owner/group of these files and you do not have the execute bit set.

Put the files back in mu-plugins and run chmod -R 755 on mu-plugins

mu-plugins is giving me the problem, but if i download into plugins directory, it ok.

then put it in the plugins folder and network activate it. Does it work then?

i noticed i can activate it as “network activated” after installing the plugins from controlpanel.

There is no need for “mu-plugins” if it can be network activated ?

Seems to me there is a bug somewhere, basically with $wpmu = 3.

Not … really. I mean, not every plugin can work in mu-plugins. If you can network activate it, the only diff between that and mu-plugins is that a sub-site can turn OFF a network activated plugin, where as they cannot turn off a plugin in mu-plugins.

a sub-site can turn OFF a network activated plugin,

Only if they are on the blog where it was network activated. ??

I keep forgetting to test as a non-SuperGrover…
