Hi Anitha,
Please complete the following steps in order to detect the problem and find its solution:
1) Try activating a standard WordPress theme for a while (Twenty Fourteen, Twenty Fifteen) and check if the problem remains.
2) Try deactivating all of your plugins except PDF&Print by BestWebSoft and also check if the problem is still present. If it is not, activate the plugins one-by-one, meanwhile checking, after which plugin activation the problem appears again.
3) Provide your System status. Follow the next instruction – https://docs.google.com/document/d/1Wi2X8RdRGXk9kMszQy1xItJrpN0ncXgioH935MaBKtc/edit
4) Let us know about the results.
Maybe, it would be better if you create a private ticket on our Help Center (http://support.bestwebsoft.com/) and provide all the necessary information there. Please include a link to this post, so that we could recall the case immediately.
Sincerely,
BestWebSoft Support Team
You might need to add rel=’nofollow’ to the print/pdf buttons in your template.
Thanks for your replu neotrope. But adding rel=’nofllow’ will not solve the problem. plugin is not generating pdfs from post. It is giving ‘HTTP ERROR 500’.
