What to do if you have a technical problem with OCS:

1. Search the forum. You can do this from the Advanced Search Page or from our Google Custom Search, which will search the entire PKP site. If you are encountering an error, we especially recommend searching the forum for said error.

2. Check the FAQ to see if your question or error has already been resolved. Please note that this FAQ is OJS-centric, but most issues are applicable to both platforms.

3. Post a question, but please, only after trying the above two solutions. If it's a workflow or usability question you should probably post to the OCS Conference Support and Discussion subforum; if you have a development question, try the OCS Development subforum.

We found an error on OCS Our conference start date is coming, and now all the articles were submitted, most of the evaluated and we are scheduling the conferences and we need to set on the system the dates and location of the presentation, but, we are not able to do this.

When we load

User > Conference Site Management > Scheduler > Schedule Presentations

The following message appears on the right side of the window:

DB Error: MySQL server has gone away

And if I try to send the information pressing the Save button of the from, the system returns me a long list of erros like this:

Hi mendesrocha,

The warning can be fixed by applying the patch to http://pkp.sfu.ca/bugzilla/show_bug.cgi?id=3756 -- but it should be a harmless warning, so I'm not sure why you're getting the MySQL error. Have you checked your MySQL error log or system log to see if there is anything more specific there?

This patch correct the error and now the scheduling of the presentations is working. Nevertheless, we still got the DB error message. I checked the error_log on the server and there we have the same message we have in the browser.

We have about 230 presentations, and the page take long time to load entirely, maybe this could be a database timeout error.

Anyway, thank you a lot!
