 * After I upgrade the YARPP Plugin today, the plugin doesn´t work anymore. In the
   Admin Panel i have this 2 messsages:
 * **Your related posts cache is empty. Please build your cache from the related
   posts status pane**
 * **Die YARPP-Datenbank hat einen Fehler, der nicht behoben werden kann.** (The
   YARPP Database got an Error, which can not be fixed)
 * If I want to build the cache, this message apperars:
    Related posts cache status:
   0% There was an error while constructing the related posts for
 * so, what shall I do, to get this plugin working like befor the upgrade?

 * @klijan – Can you check your SQL db to see if there are two tables named wp_yarpp_related_cache
   and wp_yarpp_keyword_cache? If those two tables are not there, then it looks 
   like your WP db account doesn’t have access to create those tables like it needs
   to. Were you using YARPP 2.1.6 before?
 * [@moimm](https://wordpress.org/support/users/moimm/) – to uninstall, just deactive
   the plugin from the plugin settings page and then remove the folder from the 
   server.

 * [@kiljan](https://wordpress.org/support/users/kiljan/) – sorry it didn’t work
   out with your setup. The 2.1.6 is still available for download.
 * [@moimm](https://wordpress.org/support/users/moimm/) – if you look at the HTML
   source of the YARPP options screen, do you see a couple lines of HTML comments
   like <!–YARPP error: … –>? This is some debug information which may help figure
   out what went wrong. Do you know if the db user WP is using has access to create
   new tables or not?

 * Sorry, i don’t know if the db user Wp use a access to create new table ?
    How
   i can to know it ?
 * Maybe i can create the table manually, if you say me what i must to do (i’m noob
   in db manipulation !! 😀 😉 )
 * I go to read your html comment in the HTML source ! 🙂

 * mitchoyoshitaka … i don’t find your <!–YARPP error: … –>? html comments ?
 * Where i can find it ? In the code source of a file (i have open many php files
   and find nothing 🙁 )

 * I have the same problem as MoiMM.
    The tables are missing in the db. Other plugins
   have created tables so the db user should have sufficient access. The HTML source
   of the options pages does not include any YARPP errors but there are 4 MySQL 
   errors:
 * <!–MySQL-Fehler beim Hinzufügen von “yarpp_title”: –><!–MySQL-Fehler beim Hinzufügen
   von “yarpp_content”: –><!–MySQL error on creating yarpp_keyword_cache table: –
   ><!–MySQL error on creating yarpp_related_cache table: –>
 * Firebug also throws this:
    Access to restricted URI denied” code: “1012 [Break
   on this error] eval(function(p,a,c,k,e,r){e=function(c)…
 * I don’t even know if this is related 😉
    I’d really appreciate a fix for this
   problem.

 * I am having the same problem.
 * I installed the latest version of the Yarpp plugin (3.0.4)on my WordPress Blog(
   latest version 2.7.1).
 * Unfortunately on the Yarpp Options page I get an error message indicating that
   the Yarpp database cannot be fixed. When I attempt to set the yarpp cache the
   process stops almost immediately and I also get an error message. When I look
   at the WordPress
    database I do not see the Yarpp tables that should have been
   installed.
 * I am wondering whether anyone has a possible fix for this problem. I have seen
   this plugin working on other blogs and I think it is great. I am very keen to
   get it running on my own blog.
 * Many thanks.

 * I have the same problem. I assume that this error is due to an older version 
   of MySQL. I don’t think the create statements are compatible with MySQL 4.0 (
   I have that in use). Creating the tables by hand (after removing certain utf8-
   settings and current_timestamp) worked for creating the cache, but not for using
   it. I stopped there and took the latest version.

 * Hi all— I’ve decided I’m going to make a page on my YARPP site which lists the
   SQL queries to be run in case the automatic queries don’t run (for example, if
   your WP database user doesn’t have the right permissions). I’ll post a link when
   it’s up.

 * Hi all— here’s the list of the SQL queries required for YARPP installation:

 * Mitch.
    Thanks for your last post but for those of us who have absolutely no 
   idea what those instructions mean or how to implement them, can you offer some
   alternative advice?
 * I have both the wp_yarpp_keyword_cache and wp_yarpp_related_cache tables visible
   but get the cache build gets interrupted at 48.4% everytime I try to build the
   cache. I get the following message; “Constructing the related posts timed out.”
 * The plugin is still visible on my pages, see an example .. [http://www.gadget-blog.co.uk/gaming-consoles/sony-playstation-ps3-slim/](http://www.gadget-blog.co.uk/gaming-consoles/sony-playstation-ps3-slim/)
 * .. but I don’t know how effective it is.
 * Appreciate any help.

 * [@funkster](https://wordpress.org/support/users/funkster/) – are you actually
   getting the “there was a database error that could not be fixed” message from
   YARPP?? That’s what those instructions are for. If you are able to build the 
   cache (even partially) then you most likely have no need for the manual SQL setup.
 * If you’re having trouble completing the cache, I recommend you simply keep the“
   on the fly” caching option on. Over time it will naturally build up your cache
   and there should be no need for you to manually build it.
