My FPDF was working nicely but suddenly it is making problem to generate pdf file.
Now when i am going to generate pdf it is showing an error
"FPDF error: File is encrypted!"
What is the problem? How can I fix it?
I have already tried with like this:
ini_set("pcre.backtrack_limit", "1000000000");
ini_set('memory_limit', '1024M');

I'm trying to upload a Google Colab notebook to GitHub, but I keep getting the error:
Invalid notebook
missing attachment.
I went back and deleted the line for that png but still after resaving the notebook and trying to upload it again it says the same thing just for another png.
Is there a way to fix this without deleting every png in my notebook?
Check first, as in here, if you have a a link to an invalid png in another markdown cell.
In other words, the png might not be the issue (no need to delete it).
But an invalid reference to a png with the same name might trigger the error.
So I got one thing in mind while working on VSCode. While I am using the auto save afterDelay and I am working on something and the file has some error and I rest a second the file gets saved. What I want is I dont want VSCode to save the file if the file contains any error. Like maybe a syntax error on javascript or python.
I have some code that reads pdf files. The code fails at the line :
iTextSharp.text.pdf.PRTokeniser.CheckPdfHeader() at
iTextSharp.text.pdf.PdfReader.ReadPdf()
I know from other entries that this issue is coming from some invalid formatting in the pdf. However I'm not in a position to tell my users to redo their pdfs. Is there some other way around this issue, that can allow reading of the pdf despite this problem?
If a file doesn't start with %PDF- then there's nothing to fix: the file isn't a PDF file.
However, there may be another problem: maybe you're trying to access a file that has zero length due to some problem while creating the InputStream. Another context in which I've seen this happen, is a PDF loaded from a server, where the server returned a 404 message in HTML instead of a PDF file ;-)
Whenever that exception happens, you should store the bytes somewhere, and examine them. Without those bytes, nobody will be able to give you useful advice.
I'm using fpdf library and there's no output produce after I run the code.. What's the problem and how can I resolve it?
Note: It also produces no errors, so it's so hard to fix the bug
