I. Compatibility

To work properly, GuppY needs that your web browser can manage correctly CSS stylesheets and HTML version 4.

GuppY should work properly with Internet Explorer 5.5 and 6, Netscape 6, Mozilla , Opera and many others. It was tested with Internet Explorer 6, Mozilla 1.6 and Opera 7.23, so your feedback with other browsers will be more than welcome

Please note that the functionality of the new o­n board WYSIWIG editor of GuppY requires to work with Internet Explorer 5.5 or later, Mozilla 1.3 or later and even Netscape 7.1

II. Known issues

- The WYSIWYG editor introduced with this release is very new and we are not shure about its use with Mozilla clones or Netscape 7.1
- GuppY shoud now (since version 3.0) be 100% compatible with IIS, but I did not test it. If you face trouble, to have it running quite properly though, you will have to replace the inc/includes.inc file with the inc/includes_IIS.inc o­ne (just delete the inc/includes.inc file and rename inc/includes_IIS.inc into inc/includes.inc).

III. Technical notices

1. e-mail

Some web hosts do not work with the standard PHP mail() function, but with a modified version (like Online.net or Nexen.net for instance) or with a tricked version (like Free.fr for instance, see next paragraph). As from version 2.4 of GuppY, these e-mail functions can be set up in a dedicated inc/mail/ directory.

If you write such a script for a web host specific function (see the Online.net.inc and Nexen.net.inc to learn how to proceed), the GuppY development team would be more than happy to receive a copy of it.

2. Free.fr e-mail specific

Now Free uses the standard php mail function. Then you don't need to use "protomail".

3. Files upload

Some web hosts disable the HTTP file upload functionality. Then, the Upload admin functionality will be useless. Upload your files o­n your site using your FTP software.

4. Content sharing between sites in RSS format

Some web hosts limit the PHP include() function to access o­nly internal files, not files from another website.
Then, the news sharing module between sites in RSS format will not work.

5. How to access to the mobile version of GuppY

If your site is accessed this way : http://www.yoursite.com/here/ (for example), then the mobile version (which is a lightened version of GuppY aimed for PDA users and blind people) is easily and automatically accessed this way : http://www.yoursite.com/here/mobile/. Just put a link in your web site for telling your mobile visitors how to access it.

6. Follow-up e-mail to more than o­ne receiver

An example of a function which sends follow-up e-mails to more than o­ne receivers is given in inc/mail/more1receiver.inc.
Be careful that you have to edit the inc/mail/more1receiver.inc file (with any basic text file editor) and input the additional names and e-mail addresses.
