Skipped indexation: No suitable parser for the submission file

Hi

I have installed OJS correctly.

I am getting 404 error when I am trying view the pdf but on 404 page, I can able to DOWNLOAD the pdf file.

URL:
https://sadupublications.com/journals/index.php/al-shodhana/article/view/3/2

I have checked the error log and the below is found.

Skipped indexation: No suitable parser for the submission file “journals/1/articles/9/6720689f7a7d4.pdf”

OJS: 3.4.0.7

This error is coming for all the pdf view.

I have tried by changing the pdf file name, etc but no use.

Thanks in advance

Did you uncomment one of the lines after ; PDF in the config.inc.php, like this?

; PDF
; index[application/pdf] = "/usr/bin/pstotext -enc UTF-8 -nopgbrk %s - | /usr/bin/tr '[:cntrl:]' ' '"
index[application/pdf] = "/usr/bin/pdftotext -enc UTF-8 -nopgbrk %s - | /usr/bin/tr '[:cntrl:]' ' '"

Also, pdftotext must be installed on your server and the path pointing to be inserted in the line above.
