The Cas is ok, however i cannot edit the image of the html editor with formulas and text.
When i click on

Hypotheses?
Thanks for help
Marcello,
your server might be behind a firewall or may have restrictions for Internet connexions. The formula image is generated in wiris.com server.
If the images in the test page appear ( ../moodle/plginwiris/test.php ) then the problem might be different.
If you send the moodle url we can give more advice.

Hi Ramon,
this is the test page
Info
Plugin version: wirisversion; ?>
Moodle charset:
Database charset (according moodle):
We will send alpha character to database... You should see it in both cases!
rawtext = $testchar; $wrscache->timemodified = time(); $wrscache->filter = 'wiris'; $wrscache->version = 1; $wrscache->md5key = $md5; insert_record("cache_filters", $wrscache, false); $wrscache = get_record("cache_filters","filter","wiris", "md5key", $md5 ); $testchar = $wrscache->rawtext; delete_records("cache_filters","filter","wiris", "md5key", $md5); print "After passing through the database (" . strlen($testchar) . " bytes) hex: " . bin2hex($testchar) . ", char: " . $testchar; ?>
Test 1: testing tilde
Test 2: testing tilde in forms
">Test 3: testing a simple image (1+2)
Test 4: testing a hard image (setN symbol)
Test 5: testing getting wiris cache
posted $wrscache = get_record("cache_filters","filter","wiris", "md5key", $md5[1]); // Finally, php search in database the same md5. If exists in database, it doesn't create the image, only it reloads the saved image. print "Raw text from database (parsed): " . $wrscache->rawtext . "
\n"; print "md5: " . $wrscache->md5key . "
\n"; print "Image: 
\n"; ?>
Test 6: testing creating image
Nothing else.
What url would u need to check it better?

We need to have a look at your server (if possible) to better understand the possible problem. we checked www.cyberscuola.it but we don't see the plugin installed there.
The usual problem is that your server may have some kind of firewall that prevents it to connect to an Internet server. The images are created at our server in www.wiris.com and your server needs to connect with our server.

The server is www.eda.lombardia.it/corsi

Hi, I'm Juan Lao Tebar, responsable of Plugin WIRIS development.
I have seen your server configuration and I think that the problem resides on apache or php configuration.
In test.php I see:
We will send alpha character to database... You should see it in both cases!
Original (2 bytes), hex: ceb1, char: α
After passing through the database (2 bytes) hex: ceb1, char: α
"char α" << here is the problem. You should see "α" character.
Plugin WIRIS uses UTF-8 encoding for display special mathematical characters, but your server cannot display it (is wrong configured).
The solution is modify apache configuration:
For any problem, please, report it.
Thanks for use Plugin WIRIS.

The solution is modify apache configuration:
- Open httpd.conf, apache2.conf, apache.conf... of your server.
- Search line "AddDefaultCharset [...]", where "[...]" can be anything.
- Write "#" before this line, as this: "#AddDefaultCharset [...]".
- Save the file and restart your apache server.
- Open php.ini... of your server.
- Search line "default_charset = [...]", where "[...]" can be anything.
- Write "#" before this line, as this: "#default_charset = [...]".
- Save the file and restart yout apache server.
For any problem, please, report it.
