Hi,

After installing and enabling joomsef_metabot i get

any idea how to solve this out ?

i'm using joomla 1.5.7 + Virtuemart plugin for joomsef + joomsef 3 and latest joomsef_metabot

Thanks in advance.

Hello,

well, the metabot is standard part of JoomSEF installation, so there is no need to install it separatelly. If you did that, maybe something got broken. Also, if you have JoomFish (see FAQs) or other SEO tool, make sure the plugins are not mutually conflicting.

Hi,

Should i disable "System - SEF" plugin?

and does the internal joomsef meta plugin creates on the fly meta tags and description?

I just checked my Joomsef plugin (the bundled one) and it's enable + everything is set to yes

why joomsef does not dig and creates meta keywords automatically on the fly?

Hello,

system - SEF can be left turned on, this one is not conflicting with JoomSEF.
JoomSEF will generate the default meta information entered for articles or you can also enter "own" metadata for any URL JoomSEF generates. Then these metadata may override or be appended to the original ones.
JoomSEF does not "generate" any metadata in terms of e.g. calculation the number of appearences of certain keywords and putting them to metadata.

1. because it is not its purpose and there are other tools to do that
2. because it would be very costly in terms of system resources

The metadata and description should be pregenerated at the time when the content (article) is saved. So that is not job of JoomSEF.
Second, automatically generated keywords are generally useless to help you achieve better SEO ranking. Moreovers, the crawlers are capable of calculation the most often appearing words themselves.
