I have two identically reports (diff only filters). Reports runs normally on my local comp (win7). On remote host (WinServer2008) the first report run OK, but the second report show ERROR and warnings:
...

TCPDF ERROR: Some data has already been output to browser, can't send PDF file
MySQL DB is the same, project's folder is the same for local and remote. What may be wrong? Why one report always run OK?

Are you using the latest version of nurunpdf.php?
https://github.com/nuBuilder/nuBuilder- ... runpdf.php
And what's your PHP version?

Only this request works:
Code: Select all
SELECT
mypppl.pppNPP,
mypppl.NAIM,
mypppl.PSW,
mypppl.BAZA,
mypppl.pppEMAIL,
mypppl.pppUSERNAME,
mypppl.DATECHANGE
FROM
mypppl
WHERE
( mypppl.BAZA = 1)
Any filter like: mypppl.BAZA = 0, mypppl.BAZA <1, mypppl.BAZA = 2, mypppl.BAZA = '0' - I get above ERROR !
filter: mypppl.BAZA = '1' or mypppl.NAIM LIKE 'опер%' - is OK

Try another set of brackets for the WHERE clause like:

It looks like the reason was in the fonts. If I used default "Helvetica" I get:
06.02_1.png
I changed font to "dejavusans" and get ERROR( I think, for long string in Detail section) and no Report.
Now I changed font for Detail to "freesans" - all is OK !
06.02_2.png
p.s. While I was figuring it out, I learned a lot, but I'm not sure what is useful

freesans is UTF-8.
Also hope that the header had a UTF-8 directive.
In the browser settings try to View=> Encoding => Unicode for the other fonts.
