theme id classic not found after upgrading to LR 7.0GA3

[Kim Zeevaarders，修改在7 年前。]

Hi,

After upgrading liferay 6.2GA2 to 7GA3 i see following messages in the startup log:

<log4j:event logger="com.liferay.portal.service.impl.ThemeLocalServiceImpl" timestamp="1473763885878" level="WARN" thread="http-nio-8080-exec-1">
<log4j:message>No theme found for specified theme id classic. Returning the default theme.</log4j:message>
<log4j:locationinfo class="com.liferay.portal.service.impl.ThemeLocalServiceImpl" method="getTheme" file="ThemeLocalServiceImpl.java" line="237" />
</log4j:event>

Seein that liferay 7 also know a theme with ID classic, why is this problem occuring? What should I do to fix this problem? Did I miss some step during the upgrade process?

Hope you guys can help!

Regards,

Kim

I managed to get rid of the error by changing the theme of my sites from classic to classic Appereantly the classic theme plugin ids do not match between liferay 6.2 and 7.0.

Can anybody conform this? Is there a general way for this problem without the need of resetting the theme to classi for every single site. I know I could do it over beanshell, but am wondering if there is a better and faster way?
