VERY URGENT error on line 3 php file

I am getting an error here:

contacto-pronet-lactacyd.php

that says:

Warning: session_start() [function.session-start]: Cannot send session cookie - headers already sent by (output started at /home/lactacyd/public_html/contacto-pronet-lactacyd.php:1) in /home/lactacyd/public_html/WA_ValidationToolkit/WAVT_ValidatedForm_PHP.php on line 3

Warning: session_start() [function.session-start]: Cannot send session cache limiter - headers already sent (output started at /home/lactacyd/public_html/contacto-pronet-lactacyd.php:1) in /home/lactacyd/public_html/WA_ValidationToolkit/WAVT_ValidatedForm_PHP.php on line 3

Please help! What am I doing wrong?

Based on the error I'd guess that you have a blank line of code on line 1 of the page: contacto-pronet-lactacyd.php

Php is very particular about not having blank lines of code before starting a session or redirecting.

Nop, no blank line

Please someone from webassist, can't you help me?

Upload a copy of the file referenced in the error and we can look at it.

I am attaching all the files.

I should add that this is my version of ContactForm103 translated into spanish, following your instructions from a previous conversation.

See this post for details on troubleshooting the headers already sent error:
showthread.php?t=19285

the error is pointing to line 1:
output started at /home/lactacyd/public_html/contacto-pronet-lactacyd.php:1

This usually happens if the file is saved with the Unicode BOM Signature enabled. See the end of the post I linked to for details on checking the BOM Signature.

There is no attachment, please compress the contacto-pronet-lactacyd.php file to a zip archive.

It seemed that the upload went fine, but then it appeared an error. I am trying again, but just in case it doesn't work again, can you send me an email to send the attachements to you, please?

Nop, I've tried with a .rar file, with php file and nothing:

contacto-pronet-lactacyd.php:
Invalid File

did you read this post:
showthread.php?t=19285

and check for the BOM setting being enabled?


If you need me to look at the file, compress it to a zip archive (not rar) and send the zip file.

Trying to attach 2 zip files now:

contacto-pronet-lactacyd.zip only has the php file

lactacyd.zip has: WA_Globals and WA_Universal_Email and WA_ValidationToolkit
