[TYPO3-english] rtehtmlarea problem

[Geir Nygård]

Dear list,
Please bear with a newbie for a moment, I have searched and not found any
solutions to my problem. I have created a site that runs smoothly on my
computer (wamp) with typo3 4.2.6, but when I want to transfer it to my
webhost I get problems with rtehtmlarea. This is my first attempt at
installing a live website, and I succed to make everything work in both FE
and BE, except this one problem: fatal error in rtehtmlarea when I try to
edit text elements in BE. These are the warnings/errors that come up:

Warning:
t3lib_div::require_once(/myfolder/typo3/sysext/rtehtmlarea/extensions/DefaultInline/class.tx_rtehtmlarea_defaultinline.php)
[function.t3lib-div-require-once]: failed to open stream: No such file or
directory in /myfolder//typo3_src-4.2.6/t3lib/class.t3lib_div.php on line
4689

Fatal error: t3lib_div::require_once() [function.require]: Failed opening
required
'/myfolder/ typo3/sysext/rtehtmlarea/extensions/DefaultInline/class.tx_rtehtmlarea_defaultinline.php'
(include_path='.:/usr/local/php5cgi/share/pear:/usr/local/php5cgi/include:/usr/local/php5/include')
in /myfolder/typo3_src-4.2.6/t3lib/class.t3lib_div.php on line 4689

Am I doing something wrong with the installation, or is this related to
issues with the server? I have tried emptying my browser cache and deleting
temp_cached files. There was no rtehtmlarea directory under typo3temp (so no
files to delete here), could this be related to the problem?

Thanks in advance for any help.

Best regards,
Geir Nygård
