I am using eLog ELOG V2.6.1-1681 which has 7 log books under 8 categories. Out of 7 log books, 2 are daily used. It happened that two weeks back. I modified information on two log books which were not used for quite longtime. Hence using CONFIG, I updated these log books, changing text etc. After that eLog in general started giving error. Any time when we click SUBMIT button in any log book, eLog shows page not found. That submit crashes eLog and as a result elogd service stops. Restarting elogd service, eLog operation comes back and the log which I submitted was actualy saved. Difficulty is that this problem is happening with every single submit action. 

I searched forum and learnt that upgrading eLog to newest version 2.7.8 will solve this problem. Upgrade created more problems, I was not able to open any log, authentication was not accepted. I restored that backup and went back to previous version. eLog started working but with submit error.

If any one can help me in fixing this problem
