Any Idea what these errors could be and how to solve them?

Which language do you use for your InvoicePlane interface?

ldo · July 16, 2017, 10:06pm

Hello,

I used french as language and now I switched to english but the error occured again.

musa · July 17, 2017, 1:06am

Is that a fresh install of Invoice Plane? Which version is it?
Do you have custom fields?
Can you try changing the TTFontFile.php file’s charset (with your text editor) from UTF-8 to something else?

ldo · July 17, 2017, 8:54pm

Hello,

Yes it’s a fresh installation of invoice plane.
It’s the last available version.

What I have done is:

download the installer file on my windows 10 machine
unzip the file
copy it through ftp to my linux server
run the installer
configured the software
Made some tests and found out that everything was working except this part.

Do you think I should use another format of mysql database with a different charset?
I use utf8_general_ci

Thank you

musa · July 17, 2017, 10:34pm

No, I was talking about the file’s charset, not your database’s charset (utf8_general_ci is good).
Your fonts might be corrupted, try to re-upload following folder: /vendor/mpdf/mpdf/ttfonts. There should be .tff files over 100KB there.
Make it chmod 777 if it still does not work.
I have no other clue.

Wowwwww, excellent.
You’re something like God now for me.

It works after uploading again that part.
