Some idea of what files you are trying to import might be helpful. Please read: [https://easyeda.com/forum/topic/How-to-ask-for-help-and-get-an-answer-71b17a40d15442349eaecbfae083e46a](https://easyeda.com/forum/topic/How-to-ask-for-help-and-get-an-answer-71b17a40d15442349eaecbfae083e46a)

please refresh the editor twice, it will works

I'll add mine on to here as I'm having the same problem. I've tried refreshing the editor several times but it keeps giving me the same error message as the O.P. The one I'm trying to add is this one [https://www.mouser.co.uk/ProductDetail/Bourns/PTL30-15O1-503B2?qs=MufAK3yimRO4GCiv/1T5ww==](https://www.mouser.co.uk/ProductDetail/Bourns/PTL30-15O1-503B2?qs=MufAK3yimRO4GCiv%2F1T5ww%3D%3D) I have attempted this several times now but still no success. The file name is PTL30-15O1-503B2.lbr

@GerritMax Just delete all the cache ( images and files ) from your web browser and restart the browser everything will be fine. Problem is with older version. All you have to do now is update the browser

Hello Please clear browser cache and downgrade the EasyEDA tool version Check this link : [https://docs.easyeda.com/en/FAQ/About-Update/index.html](https://docs.easyeda.com/en/FAQ/About-Update/index.html)

@JLCPCBsupport & [Mounish Patel](https://easyeda.com/mounishseetha), A BIG THANK YOU to both of you, it finally worked.

Hi Andy could you tell me where the undo Button is? it doesn't appear on the tool Bar since this strange Update...

@B2Sisko, It is poor forum ettiquette to tag a totally unrelated question of a different category onto an existing topic. If you have a question, please post it as a new topic in the appropriate Category.
