Many of using wp-cache seem to have the problem of NOT being able to include any dynamic plugins once wp-cache is enabled. mfunc does not work for dynamic plugins. It sure would be lovely to figure out a workaround. Please, please, if anyone has one, post.

I think i solved my problem. It was a setting in the server. Now I would like to ask if it is possible to make one widget dynamic? I am not able to do so for my online counter. Or how can I make my sidebar dynamic?

I followed everything in the manual install but i still get this error:
“Couldn’t write to: /home/httpd/vhosts/…../blog/httpdocs/wp-content/cache/wp-cache-bade0af957b50b069f1c002b8a0dd3d0.html”

I have set the directory to writable but still cannot cache.

Please help me

Well, I’m somewhat embarassed to admit I’m stuck on:

Upload to your plugins folder, usually wp-content/plugins/ and unzip the file

Although I have installed dozens of WP Plugins, I have never had to do it this way and have no idea how I would go about it. When I unzip the file on my hard drive I see no sign of any wp-content/plugins/wp-cache/ directory.

Also, having read all 373 comments carefully, I also don’t see any useable instructions for inserting a symbolic link, despite the fact that people continually ask about it. Like the vast majority of WP users (I expect), I do not have SSH or Telnet access to my host server.

Can this symbolic link be made using .htaccess and if so how?

Um, let me try that one more time. Werid!

Hey,

Finally figured out my problem.

wp-settings.php was missing the following:

add:

`// For an advanced caching plugin to use, static because you would only want one
if ( defined(’WP_CACHE’) )
require (ABSPATH . ‘wp-content/advanced-cache.php’);`

after:

`// Change to E_ALL for development/debugging
error_reporting(E_ALL ^ E_NOTICE);`

Why? I have no idea. Really werid!!! Just glad I finally figured it out.

About darn time. hehe Working pefectly now.

Take Care,

Will

I installed it and got the blank page problem but corrected it with the ob_end_clean to ob_end_flush trick and it works great.

Hi everyone,

First of all i wanted to let you know that i really appreciate your work. I run a pretty large non-commercial site and so wp-cache could prevent me from buying dedicated webserver.

I do have some questions though. As i said i just installed the plugin. I think it working since i see the cached pages multiplying every second. However i don’t know if i installed it correctly. My index.php is causing the most problems according my webhoster, sometimes it seems to take up 75% of the shared CPU power. Therefore i installed your plugin. The front page loads up 7 excerpts, 30 headlines, 37 comment counts and a lot more. If those queries are cached it would be an enormous power saver. Instead of loading all the queries constantly i want it to load it from the cache and refresh it every 30 minutes. However, when i post a new article, it’s right on the front page on the front page, the same counts for comments in posts. Of coarse iam glad it is there inmidiatelly, that’s the purpose of a news site, being fast. But it leaves me thinking the index isn’t cached after all. Or is it? You can find my website on http://www.nieuwszicht.com It probably helps a little bit if you see the site visually.

I also have the UTF-8 problem. I installed version wp-cache-2-0-17at first and then installed wp-cache-2-0-2a to fix it. It doesn’t seem to help unfortunately.

Here is my PHP and SQL information, perhaps it helps:

Operating system Linux
Linux kernel version 2.6.9-22.0.1.ELsmp
Apache version 1.3.34 (Unix)
Perl version 5.8.7 (more info)
PHP version PHP/4.4.1 (more info)
MySQL version 4.1.14-standard

My apologies for the bad English and thank you in advance for answering the questions.

how do i insert a symbolic link?

By: digitalfrog

haaahaaa….

Looks like there is a fix:

1. Open wp-cache-phase2.php file* in your favourite text editor
2. Find out wp_cache_ob_end function
3. then inside that function find out line with: ob_end_clean(); (it should be line 219 or about)
4. and finally replace that line with: ob_end_flush();

found it here: http://wordpress.org/support/topic/48777

Symbolic link - comment #300 came closest but I still have no idea what this means… type it in a CMD prompt window? I think not. I’m using Filezilla to ftp up to my ISP’s host (I, like alot of others, do not have my own server) so how do I get this working?

This is the error I am getting on the options panel:

advanced-cache.php link does not exist
Create it by executing:
ln -s /WP/wp-content/plugins/wp-cache/wp-cache-phase1.php /WP/wp-content/advanced-cache.php
in your server

I manually add this advanced-cache file to the server and all the files are 777 but I still get the same error.

I see 4-5 prior requests for help on the symbolic link step, please be very explicit for us noobies so we can all use this. TIA.

First, I’m please that this plugin exists because I run my blog on an old PII with 256megs of ram and this should help a bit
I installed the latest version and I get the white page issue like a few others.
Seems a reload of *each* page helps, but if someone adds a comment or so the articles are not showing anymore.
I manualy went to each article and did a reload, but it won’t matter as tis will break every time someone will add a comment

Looks like we are a few with this issue, anyhelp is appreciated.

I’m trying to use a dynamic program like Democracy (poll) with this plugin. I think I’ve gotten close but I haven’t quite figured it out(it gets cached, or throws errors). Any suggestions?

I’ve:
- enabled democracy long enough to create a poll.
- disabled wp-cache …
- disabled democracy …
- then, called the plugin manually from the sidebar as described on this page:
elliottback.com/wp/wp-print.php?p=914
- re-enabled wp-cache
- answered the poll
- it all seems to work until I return to that page and then I get a fatal error because this function is undefined (presumably wpdb):
———————-
$poll_question = $wpdb->get_row(”SELECT id, question, voters, allowusers FROM {$table_prefix}democracyQ WHERE {$where}”);
———————-
Which makes sense since I call the plugin so late in the game.

Is it possible to work around this … call a dynamic plugin successfully while using wp-cache?
