Download of datafeed failed, please check feed url

Hello,
I would like to try this component. But I've got a problem with importing feeds.

I've got -- Download of datafeed failed, please check feed url and write permissions on cacheno Items ?

I tried to make new import with same setting like Addition Elle:CJ Feed but i ve got same result.

Download of datafeed failed, please check feed url and write permissions on cacheno Items ?

Cache of joomla is setted on chmod 777, where is problem? Pleas help me. Thanks Vana

did you try the other feeds?

Yes I tried other feeds. But without success. This component I see first time and I dont know how to. So I tried import examples (for example Addition Elle:CJ Feed, I published it and i did Uprgrade Now feed) and I've got this warning: set_time_limit() has been disabled for security reasons in /data/web/virtuals/49359/virtual/www/subdom/slevy/administrator/components/com_datafeeds/cron/feedcron.php on line 93

The warning shouldn't be a blocking issue.

the 'Addition Elle' is not working correctly, please use one of the other, enabled feeds for testing.

the test feeds are routed thru my own server and I see requests for feeds from slevy so that part seems to work

ensure the directory administrator/cache is writable for the webserver.

Ok I tried to make other feed. Example Tropic travel www.gryla.biz/feeds/xml.tt.topictravel.xml . I setted everything as Topictravel:tt Parser/Class": TT V1 Filter/Callback: reizen_cb
I've got:
Tropic travel

[description] => Idealer kan haast niet. Vanuit uw heerlijke vakantiehuis gaat u iedere morgen te voet uw stokbroodje en croissantjes halen voor het ontbijt, in één van de mooiste stadjes van de Dordogne: Belvès. Degenen die het slechts 500 m lange pad naar Centre ville te steil (omhoog) vinden, rijden met de auto even om (1 km). Belvès is een schitterend behouden, middeleeuws bastidestadje met goudgele geveltjes en talloze monumenten. Het winkelen op het marktplein en in de straatjes rondom, is een feest. Talloze restaurantjes, barretjes en terrasjes. Fietshuur en tennisbaan ter plaatse. Dordogne-rivier op slechts 5 km (kanoën), die hier op z'n mooist is.
