Having a few problems with an infected hosts file which I'm trying to get help on a different forum, so I cannot use localhost - have to use 127.0.0.1:8000 - so not sure if this affects this problem...
I have installed 2-3 templates and each time Joomla says for example, the parameter file templates\rt_meridian_j15\params.ini is writeable, I then go and change bodystyle or colour and ity becomes unwriteable..... so any changes do not actually seem to work...
thanks - you are quite correct - I forget to flush the cache - which is why the changes do not take effect.
The changes are made correctly on the template.
Template params.ini file becoming unwriteable when you save a change has been a long standing problem for me, and not one fixed by reinstalls. The normal fix has been to chmod the params.ini file to make it writeable by user - e.g. 644, 755.
Basically, you change the Joomla administrator\components\com_template\controller.php file and replace the three occurrences where permissions are set to 555 to be 755.
Not sure if this creates any security issues, and there doesn't seem to be any responses from the Joomla developers on this issue. So use it at your own risk.
