3. Common problems

3.1 Translations are not working

If you have gettext support in php, translations will work only if you have appropriate system locale.

3.2 Some words are not translated

This is the way gettext translations work. If translated string is not available - English version of translation is used.

Possible causes are:

• translation that you are using is not fully translated.
• strings belong to non-core SquirrelMail plugins

3.3 "xxx character set is not supported"

"xxx character set is not supported" errors may appear when you switch to some translations. This usually means that your IMAP server does not support charset that is used by translation.

Error can be disabled by setting following SquirrelMail options to false:

• 4. General Options -> 11. Allow server thread sort (it is not enabled by default)
• 4. General Options -> 12. Allow server-side sorting (not enabled by default)
• 4. General Options -> 13. Allow server charset search (enabled by default)

There is one exception. If you are using Turkish translation, you can get similar errors even when your IMAP server supports ISO-8859-9 charset. This happens due to different small letters to capital letters conversion rules in Turkish. See SM bug No.690625 and http://www.topolis.lt/squirrelmail/turkish.html for more details.

3.4 "Invalid range end in /usr/share/squirrelmail/functions/i18n.php"

If you are using SquirrelMail on Linux RedHat v7.3 system, sometimes you can get error:

Warning: Invalid range end in /usr/share/squirrelmail/functions/i18n.php on line xx

Problem can be reproduced only on RedHat 7.3 or RedHat Advanced Server 2.0. It happens only if UTF-8 enabled glibc locale is used. this means - ca_ES, cs_CZ, da_DK, en_CA, es_ES, es_US, et_EE, fi_FI, hr_HR, is_IS, lt_LT, lv_LV, no_NO, pl_PL, sl_SI are affected. Emails that produce warnings use other encoding than is set in user's locale.

The problem is in broken glibc, apache or php patches used by RH. System doesn't like regexp ranges at \237-\240 (octal numbers). decimal 159-160. Latest SquirrelMail versions tries to avoid this error.

3.5 Latin letters instead of the ones that are used by translation.

FreeBSD requires full locale name.
