yes

you have the PHP variable "short_open_tag" set to Off and it should be On. just change that in your php.ini file and everything will work fine

I got it.
Thank you so much ?
PS: But would you mind provide which file use this short tag code than i can edit it ?
Because in some case i cant edit php.ini. In current i'm trying on localhost.

you should always be able to modify php.ini file, either if you use an external (paying) server, or you are just testing on localhost

if you dont know where your php.ini file is, just execute the php command phpinfo(); and this tells you where your php.ini file is located.

you are probably using Apache. have you installed xampp, for instance?

No
I mean in moment testing on localhost is ok.
I can control everything. But what if i use another hosting provider w/ custom php.ini is allowed.
In this case i need to mod the source code

well, I tell you again, I think even in the cheaper hosting provider service (as mine! ) you can always upload a php.ini file into your site's root, and the server will read it automaticly.

but anyway, this error you get is located on file

administrator/components/com_muscol/helpers/helpers.php

you'll see the beggining php tag is "ut you'll get others. so, what you can do is replace AAAAALLLLL tags!!

I see you must probably be developer.. so you know how to do it

in case you dont: if you use Dreamweaver, for instance, CTRL + F (CMD + F in mac) and replace all the short tags to standarf tags in all the folder

administrator/components/com_muscol/

and also

components/com_muscol/

good luck!
