will have no errors and you can turn on from 4images cpanel who`s online and really works!
Best regards to monty who helped me fix out this problem!
maybe someone else will need this ,that`s why i posted!
Free open source code for everyone!Enjoy!

i`ve downloaded the 4images standalone...
apllyed the patch from bbpixel here is the link of the patch:
http://www.bbpixel.com/m-wfdownloads+visit+cid-6-lid-32.html
after i`ve instaled succesuful is giving me this error on the module:
DB Error: Bad SQL Query: SELECT s.session_user_id, s.session_lastaction, s.session_ip, u.uid, u.level, u.uname FROM xoops_session s LEFT JOIN xoops_users u ON (u.uid = s.session_user_id) WHERE s.session_lastaction >= 1115491992 ORDER BY u.uid ASC, s.session_ip ASC
Unknown column 's.session_user_id' in 'field list'


i`ve cheched with phpmyadmin the database and also finded this error:
rodisco_xoop.xoops_users check warning Found row where the auto_increment column has the value 0
rodisco_xoop.xoops_users check status OK
rodisco_xoop.xoops_visit_user check status OK
what is the bug on that patch ?can someone help me figured out and fix this error?!

hello to all,
i`ve used too mambo and XOOPS too !
i`m using XOOPS because from the first time i`ve installed i fall in love with xoop`s,also i love this great community that has been created by xoops!
everytime that i need supported on XOOPS to do something or to modify something ,somebody from this forum helped me i think the XOOPS will be revolutionary if we will keep up the good work with ideas ,promoting ,meeting and supporting XOOPS developers!
For the best off all,Free open source code Rulz!XOOPS COMMUNITY RULZ i don`t think there are any communication problem!Mambo doesn`t have and will never have the facilitiest of XOOPS and will never have the support that XOOPS have it and will have it more from the users and from people all over the world!Mambo is nice i admited but XOOPS RULZ!
Best whises to all xoopers all over the world and for herko,monty-best regards and keep up the good work !

from where can be downloaded the module 4images for xoops?!

you don`t need an module to do that!
just go in XOOPS system admin-blocks and aadd a new block
content type:html
paste the html code of the flash banner you want to show in the block give a name to the block for example:advertising or any other name make it visible:yes;
and then submit and you will have the scrolling flash in the block...!

hmm if anyone gets this module or an link for download it pls share it to uss too!best whises...

i`ve contacted them but no answer...hmmm anyone knows a link or something to download the module called coolmusic???!!

anyone have that module coolmusic?or can post a link to download it and try it?

ams 2.41 can link to newbb for discussion ...
how to link articles to be discuted in ipboard ??!!

so the admin files they are ready or ?!
