Can´t run cron or clear cache with Apache Solr activated

You updated it from which version? Did you check your error log (admin/reports/dblog) to see what errors were logged when attempting to run cron/clear cache? Try deleting and indexing your content.

What apachesolr modules are you running besides apachesolr? What happens if you disable them and delete/reindex?

Hmm. K. Maybe ping the maintainers of Solr Multilingual for feedback.

Maybe multilingual has gone out of sync with the latest apachesolr 7.x code?

I have the same problem: 7.9 core, unable to run cron, rebuild permissions or clear cache after activating apachesolr multilingual, latest dev version as of dec 1, 2011. 7.x-1.x-dev. Additionally I cannot reach the /admin/structure/blocks page at all. And I cannot do automatic translation updates.

I had activated apachesolr autocomplete, faceted navigation for search, also and have dis-activated them - no change.

The only thing bizarre about mysetup is that I had previously installed fuzzysearch and cannot dis-activate or uninsall it. I also therefore cannot dis-activate Search API or uninstall it.

I did wonder about box for Disable Dat Dir setting - I can' t even understand what it means really, but when nothing worked after enabling the multilingual apachesolr I removed the check in the checkbox (i believe it was there by default) and did delete the index, download the two .xml files and the .zip file, extracted and uploaded them to the server, and restarted solr ... but still the same problem

I have put the following as the directory for up to date debian squeeze 64 bit:
${solr.data.dir:./usr/share/apache-solr/example/solr/data}

I am new to this - is there a problem still using Jetty and the /example/ directory - this seems strange.
Solr is up and was working fine before installing multilingual ... however it was not finding or indexing added country and region use fields added as taxonomy terms in separate taxonomy vocabularies.

In the configuation on the multilingual tab, I was unable to check the empty box that is used to index taxonomy, and could not find the module that needed to be downloaded - the link let to the insternationalization module which I already had successfully running with taxonomy translation enabled - thus your module is not understanding that I had already enabld that...

I tried adding and enabling table_translation, but it did nothing - also I have already set up multilingual site and have taxonomy and string translation enabled in modules - buy solr is not seeing that data - the added fields in the user profile data.

Any help would be greatly appreciated - as I will want to use this module a lot and perhaps help once I understand wha is going on here.

I am also getting the ollowing errors now:

Notice : Undefined index: body dans ApacheSolrDocument->__get() (ligne 304 dans /var/www/clients/client1/web17/web/reseau/sites/all/modules/apachesolr/Apache_Solr_Document.php).

and

Notice : Undefined index: title dans ApacheSolrDocument->__get() (ligne 304 dans /var/www/clients/client1/web17/web/reseau/sites/all/modules/apachesolr/Apache_Solr_Document.php).

---------------------------------------------------

Disabling the 3 apachesolr_mulilingual modules removed the problem, but I'd like to use the module once it's working.
