What ftp tool did you use? We have had probpems with one or two corrupting files – notably FileZilla.

yes i did use fille zilla.

Should i delete simpel press and use a nother ftp client ?

And if zo wich one should i use ?

Thanks

I think it would be worth a try yes.
As to which one I would just recommend NOT using a browser based one. There are many, many out there. personally I use Cyberduck which is available for both the Mac and Windows. It works for me.

I deleted and re uploaded again with cyberduck still the same problem.

Simpel press hangs at install. 

then it might be that the javascript is conflcting with something else. Any chance you could briefly switch to the Wp default theme and try installing with that running?

curently using 

Twenty Twelve
 

Nouw my webiste looks like this :

http://websitemakenforum.nl/

After doing what? There is no WP theme being loaded. Is this after SImple:Press gets installed or something?
Is your WordPress installation actually good?

afther chaning to the twenty twelve theme. 

How can i see that my wordpress install is good ? 

I probaly know the problem. Ore atleas what caused the problem. 

On this website i’m using a database from another website.   

I did make a kopie of the database and uploaded it to my new website

I changed the wp-config.php file  by adding this 2 lines of code :

define(‘WP_HOME’,’http://websitemakenforum’); define(‘WP_SITEURL’,’http://websitemakenforum’);

And then i changed the data base details in the wp-config.php. 

Did something go wrong by changing the database ?

The strainge thing is when i activate my other theme from elegent  themes every thing is wurking correct.  When i activate twenty twelve there is a big error.

well the problem is fixed.

I did google on how to change the database and my hoster did not tell my that i neaded to change wp-options they only telled me to change wp-config.

Does that mean installing SP is good as well now?

yes simpel press is wurking correct

excellent. Thanks for the update.
