Uploaded Joomla!1.5.8 on my site here. Now cant install any add-on
1. Zlib is not installed. Well then, using "install from folder method".
2. File manager can unzip only if zip is in root folder (when using FTP to upload all the files without archive is too slow). Well then, zipping packets with all the ways included (i.e. 'tmp/1') and unzipping from root folder here.
3. Now when trying to install component it says "cant create 'htdocs/components/bla-bla-bla' folder". Sometimes it says "zlib is not installed" instead.
4. Tried to set up FTP connection in Joomla configuration - JFTP::connect: Could not connect to host "corax.uuuq.com" on port 21 (with my login and password). When FAR manager can.
5. Allright then, connecting FTP using login:password@corax.uuuq.com string. It connects, saves config.
6. Trying to install Joomla add-on. Now there are two new fields - FTP login and password. When filled, it says "cant connect to login:password@corax.uuuq.com", "cant create 'htdocs/components/bla-bla-bla' folder", when not filled - only "cant create 'htdocs/components/bla-bla-bla' folder".
So could anyony tell me how to install Joomla! add-ons here???

okay just a few things
you have to install add-on's and such manually
and you cant access ftp via php here you have to use a external client or www.web2ftp.com

What he said. And which FTP program are u using. Cause at this very moment I'm uploading my Joomla client. And its going pretty fast. You can't expect it to be done in matter of seconds. It takes time. Be patient. Let it upload and take some time. Play a game or something.
